PAY BACK MY R399 ASSEBLIEF

I joined Vumatel on the 30th of March 2025 and paid the subscription fee R399.00 and I was told the WIFI will be installed within 7days, instead of installation I received a username and password that the WIFI was working. I called and informed them that there is no router in the house and the agent informed me that according to the system the house is supposed to have a router. She then informed me that I will need to pay R900 for reinstallation and I told her that I would rather cancel. I was then told it will take 14 working days which never happened. I've been calling constantly without any positive outcome. I later received an email from PAYFAST that a refund will be in my account within 3 days and I responded to that email as to which banking details will be used, because I did not submit my banking details. I called PAYFAST and I was advised to contact MERCHANT and I did, the Vumatel agent advised that I send my proof of banking details which I submitted on the 22nd May 2025 and till now I still have not received my money.
