Refusing to give me my refund

When I started paying for wifi I paid for the 28 subscription but I was never sent the username and password until I had to do a follow up. only then I got those details and by then it had already expired. So I paid R395 for nothing. Then now I paid into a Std bank account that I got on their chat bot and when I called I was told I wasn't supposed to use that bank account so I requested can they allocate that money for the next 28 days they said no they can't. They will refund the money. its been 2months I keep calling they say they will call back. I am still waiting to day. BAD SERVICE
