Really bad service

I first reached out to Intec on the 23rd of July 2020. By the 27th of July I had paid all my registration fees etc and signed all documents. The guy that helped me (Loyd) was extremely quick to answer my questions. Until the minute I paid. As soon as I paid he stopped responding. Once I paid I was told 2 weeks and I would get my login details. By the 13th of August I still never had logins. I followed up and got my logins on the 19th of August. When I logged in there was no study material. I emailed him again and he told me it would take a few days. By the 25th of August there were still no details provided with regards to studies and I called them. Eventually got through to someone who told me 2 days. It's now the 1st of September and still I have absolutely no study material or any insight nor has my debit order gone off. At this point I want to cancel and go elsewhere. I've told them this but obviously don't get any luck there either.
