Telkom sucks....

I took out a contract with Telkom Mobile for the pocket wifi. The contract expired a while back and ever since I was paying it on a month to month basis. I called the call centre to cancel the contract in December 2017. In March 2018, i called the call centre again to find out why my account is still being debited by telkom mobile every month, and they confirmed with me on the telephone that the account was closed in december 2017. Todate, which is now june 2018 and telkom mobile is still debiting my account. Can someone from telkom mobile please contact me to sort this out and give me my refunds please. Please contact me by email please, **********
