Disgusting service from cellc escalations

I am livid at the level of service i received from Cell C customer services (escalations dept) they trying to over charge me for a contra t, which i didnt even know was a contract But a month to subscription which was offered toe by a retentions agent after i called in to cancel the contract with them. I requested call records whereby i was informed, that i will be charged a penalty fee of R70 for an unpaid debit. The escalation agent Deborah, calls to say there is no call rec but i was advised. I asked her if she listened to the calls she said no?! What type of escalations is this. I have logged a query twice & both times these consultants are closing off my query without a resolution. This is unacceptable & extremely unprofessional. What kind of service is this?! I requested to be contacted by a Manager, i was told that she does not know when the manager will call me. Clearly, CellC does not take me seriously or think that my query is important! I want this damn R29 debit cancelled immediately & i dont want their minutes on the 1st of April!
