Awful customer services and accounts department

I have been a client or customer of Teljoy for a period longer than 3 years. Recently i took over ownership of a product. After numerous phone calls and emails if i may add. I however now struggle with cost being added onto my account each and every month now costing me a declined debit order as well as bad credit rating and unforeseen bank costs due to Teljoys bad accounts department. I have escalated and reported this matter to Account as well as customer services but I am still waiting on their promised reply and solution to my problem. I now sit with a bank account which reflects a negative amount as well as my application with SA homeloans which will be decal ONCE AGAIN due to Teljoys inability to sort out my account. I was told earlier that for some reason I am part of Teljoy club which i told the consultant i never ever agreed to or ever paid for. She was adamant that this pushed up my installment this month which if i mau add was only emailed to me yesterday. On the day of the stop orders deduction from my bank Account. I do not wish this situation on any loyal customer. Teljoy certainly lost a good and loyal customer this time.
