No response and *********

I went to change my banking details at Germiston goldenwalk Telkom and asked my debit should be done on the last day of the month. DEBIT went off still for charged 202.70 same applies to last month same happened. Furthermore I took the *** contract in october 2018 and still my contract is being charge for over 24 months. Have been querying this and I am not getting any assistance. Case no: ***5 still pending and case no: ***4. I have visited the greenstone telkom several times and still not getting ant assistance. I refuse to be paying debit bouncing fees please change my account to cash payment and I refuse paying for a contract 28months. I will not accept the further debits and being held accountable for some people's incompetence. I have asked for an escalation process and no one seems to know what to do and not I must suffer for this. Please urgently rectify and credit my account with the extra money you've been charging me for your incompetence.
