No experience in cleaning or post renovation cleaning

We contacted Paul from Extreme clean for a "post-renovation clean up", I requested for a site visit, but Paul response was I 've being this for 23 years, I will send a quote, reluctantly I trusted his response and booked the service, he initially wanted the full payment, which I found out of place as I needed to judge the quality of work, so I paid a deposit instead. So the teams arrive about 1:45 min late, they did not have the correct address, (yet I have them the correct address) the cleaning chemicals that was brought in was sunlight liquid and handy andy for a post renovation clean up!!!, the teams could not remove the access cement, grout from the tiles etc. They did not take out the vacuum cleaner to suck up any of the dust, we told them do not use a laminate cleaner if they not going to clean the floor first, the floor was not buffed out and is now totally sticky, I proceeded to give them a grout off product to assist with the floor only to get the access grout, cement off, just for the tiles only and I showed them exactly how to use this and yet they took the same product and wiped the chrome taps and fittings, thereby destroying this. I contacted Paul and he was not bothered to come to site to check and continued to blame me for giving them this product together with assigning blame to his staff members. For a company that offers post renovation services I find they have no experience whatsoever. I would stay away from this company.
