Failed recovery and not true to their word of no recovery no payment

On the 04/05/2023 I made a huge mistake by formatting my NVME drive and I did not check my back ups. As a result I lost my entire financial system and my email since 2013. On the advice of my IT company I contacted Intratec for Data recovery services. My device was collected and I was quoted on the 10/05/2023 R5577.50 I was also told if they fail the recovery and there is nothing recovered I wont have to pay. I also specifically gave them the exact files I was looking for with dates and exact file names, it was a backup of my financial system and my latest datafile for my email. I made payment as per their request on the 17/05/2023. All went well and I was informed on 22/05/2023 that they recovered around 902gb of data. I did send out a destination drive to them. I requested a remote viewing but was denied since all the machines had jobs on them according to the contact person. On the 30/05/2023 I was informed I can arrange collection of both drives. I informed them on the 01/06/2023 that the information on the drive was current installations and none of the info is the info that was lost during the format. They insisted on reopening the job and send a courier to collect the drives again. This is were it started going downhill. The drives was collected as arranged, and on the 8/06/2023 the reception contacted me and asked “Was this ever collected?”. I was a bit surprised at the question to which I informed her yes it was collected. She seemed surprised and responded “The technician has informed me that he is redoing all scans“. On the 13/06/2023 if was informed that the destination drive was ”faulty”. I insisted on doing a remote viewing before I incur more expenses on a recovery I already had my doubts about. The remote viewing was arranged for the 21/06/2023 that was almost seven days after I requested the remote viewing on the 13/06/2023. I downloaded anydesk as per their instructions and waited from 9:30 to 11:00 for our arranged 10:00 appointmet. They missed it with no excuses or apologies. I had to rearrange meetings with clients to do the viewing. On the 23/06/2023 after a lot of effort from my side I was able to do the remote viewing. This is after their tech did send me a physical location and was not even aware that it is a remote viewing. Once again they failed to recover anything that was useable to me, this time they could not even recovered current installations information of the drive. They then insisted that they reopen the case again on the 30/06/2023. Against my better judgement I reluctantly agreed. This is where it all went even further downhill, from the 04/07/2023 I had to request constant feedback or I wont hear a thing from Intratec from the 04/07/2023 to 31/07/2023 it was always the same the tech is still scanning for the files, they have by now given up on my financial system and was only scanning for .pst files. A remote viewing was arranged for the 01/07/2023 which then was canceled. At this stage I insisted on a full refund as they are now just wasting my time and they failed to recover anything they did not want to do a full refund and I was refunded 70% after negotiations. Also the manager I spoke to BRandon Koopman admited on WhatsApp that the recovery was a failure. I accepted this reluctantly as this was going back and forth from the start of June to the beginning of Sept when the refund was finaly paid after many voice notes and complaining. Being ignored for weeks and then get a short answer of it will be paid. I will never ever recommend them to any one person, nor will my IT company again recommend them or use them as he almost lost my business as well. I still feel I needed to be refunded in full but I know it is a pipe dream. I ahve all the email trails and all the WhatsApp messages to proof everything. I am higly disappointed in the service I recieved and their reluctancy to pay me back even after they said no recovery no payment and at their own admission failed the recovery.
