Deductions

Good day I noticed that Telkom has been deducting money from my account and I haven't used my sim card for 3 months due to technical difficulty which I've experienced for months.They deducted money from my account at the end of July and I don't know why...I just had a conversation with a credit consultant and he mentioned that I have a contract with Telkom and an outstanding balance which is absurd.I have tried to contact the call centre and due to circumstances as I've been informed there are delays...Could you have your team work on this because I am paying for a service that I'm not utilising.I haven't used this sim card sinelce April and have paid every outstanding airtime balance..Why does this service account reflect ony credit report.?Kindly rectify this error and reimburse me with the money you took from my account with no reason as I know that I don't have a contract and I have not been using the sim card.The cellphone number is ***..Thanks.
