No Service from Service Provider

I have a holiday home in Ballito. Whenever I go to stay there, I contact Access Point Technologies and ask them to switch on my broadband/fibre/internet service. This I did on Monday 9th December by a personal e-mail to my contact at Access Point. He informed me that, although he no longer works at Access Point, he would see that the service was restored in time for my Wednesday 11th December arrival. Apparently, his powers of persuasion have deteriorated as my service wasn’t on when I arrived. On Thursday 12th, I phoned Access Point call centre and explained my situation. I was told that my query would be attended to but the gentlemen in the call centre couldn’t tell me how long it would take. The following day I called again and spoke to Ian and he could find no record of my call, so I went through my request again, I explained that I needed the facility to run my business and pay salaries, and he promised it would be marked urgent. When I phoned on Friday and spoke to Hein, he said he would speak to his manager and phone me back. He ‘phoned back a few minutes later to ask what type of service I had but I never heard from him again. When I ‘phoned on Saturday, Sunday and Monday the call centre voice eventually told me I should send an e-mail or contact their website. Unfortunately, it didn’t take any notice when I pointed out that I didn’t have any internet by which to achieve this. It also appeared that I was dealing with a company called Link-up who had taken over Access Point (at least from a service point of view). On Tuesday, 17th December I called again at 9h15. Nelius picked up the call and I asked to be put through to his manager. He put me through to a gentleman who called himself Hannes and who informed me that he was a director of Link-up. He explained that I needed to put my request in writing and that if I did that (by sending him an e-mail) he would have my service switched on in 15 minutes and I should call him back in 15 minutes if wasn’t working. I sent the e-mail and ‘phoned back an hour later to be told that Hannes was in a meeting but would call me back as soon as he was available. This happened around 11 a.m. at which time he told me that I would have to pay in advance (something I had never been asked to do I the past) and Access Point accounts department had sent me an invoice accordingly, Some time later I received an invoice (for what I assumed was 1 month’s service) which I paid immediately using my telephone banking app. (Access Point being one of my stored recipients from previous dealings). On Wednesday I sent an e-mail asking when I should expect to be connected – no response. By Friday I still had no service (or any communication) so I contacted Hannes (who turns out to be the Managing Director of Link-up). He responded to say that a) He cannot assist me and b) he has no authority to switch on client accounts. [Somewhat of a demotion after being able to switch on my service in 15 minutes a week and a half earlier]. I then wrote back to him and the Accounts department at Access Point asking for my money back. On Saturday, he responded, stating that he thinks I am confused and stating that it was my fault because Access Point hadn’t received the bank’s proof of payment (despite the fact that I had sent him a copy as well as the one to the Access Point e-mail address that they have always used in the past). He suggested that I sent another (3rd) POP to a different address at Access Point with a copy to him and he would escalate the matter. This I did on Sunday. First thing Monday morning I called Access Point again and the second time I called, a technician ‘phoned me back telling me that Access Point was closed until 5th January! (and, therefore, I could not expect to get connected until next year).
