Unfair treatment by Mondo(Telkom)
Hellopeter

My name is Bongani Prince Mbatha. I was offered a contract Telkom cellphone by Mondo in 16 August 2021. An agreement was that they  will deduct R175 for 24 months. End of August i waited for debit order to run, but nothing happened. I kept money in my account for September, on the 27 of September I received a message from them stating that the debit order was unsuccessful due to insufficient fund. They sent me a contact number for me to contact them. I tried to call them so that they will let me know how much are they expecting to get from my account. The number that they sent me is not working. they have even blocked my sim card, I am afraid that they will  end up blacklisting my name. I'm willing to continue with my  contract with them, but they don't communicate. 
and they number that they gave me is not working. I don't its fair for me to be treated this way. They should have communicated with me and find out if I can be able to add money in my account and they deduct again. I don't know where to find them and make arrangement with them. I am very much frustrated

Kindly assist as I am not disputing to make payment.
