Terrible customer service.

I got this msg from you tenacity : MS MATHANGANA, your ACKERMANS SOUTH AFRICA acc remains unpaid and will now be referred to a specialized dept. Pay R1639.29 Today at ABSA Bank into Tenacity Financial Services (Pty) Acc No: ***, *** or Visit https://bit.ly/30Vo50x for instant EFT. Call ***/ Whatsapp ***....... I then sent the WhatsApp to enquire more. And wanted to settle my balance. When I asked for an email to send proof of payment I was told it's not necessary, I must send it via WhatsApp. So I sent it. It was not acknowledged. I asked if you have recieved my payment , there was no response! The next day I asked another question, I was still ignored! Am really ****ed with their services, because now I dont know if am beng ****med or what will the *******ion that is goin on in South Africa.
