Bad service

I have a contract with Telkom, I was assistant by the lady called Nicole at Canal walk branch by entrance 4, she is unprofessional never mentioned that my Acc will be locked when I was in store to change my debit order date. Few weeks later my Acc was locked, not shocked because she was busy laughing while busy assisting me. Went to the Telkom store I was told to make a payment of R200 and I did. Then end of April they deduct on my account R403 and it does reflect on my baby statement but doesn’t reflect on their side and they locked my account again but I did pay. Am sick and tired of this.
