Double charge/double deduction/pathetic service

Most **** customer service ever,I have been in they branches on numerous occasions, called,even got one of they agents to log complaints call and even received a case number,but still my query hasn't been attended to..I received a call from the call centre offering me a new contract telling me that I was due for an upgrade according to my knowledge I knew that I was due for one,but not so soon!!!as I listened to the next deal I was content with it,but I remember myself asking him to repeat that I will not be paying for two contracts and he agreed,since the that day I've been paying for 2 phone's instead of one,infact in one month I was billed for 3 times and twice the amount of money..now I sit with reversal fees and bank charges that are extremely high which is unacceptable...funny part is I get a call from one of they agents and he's exact words were I'm calling you to offer you a new contract,and not for your query that has been submitted...going onto a Telkom store is one of worst cause all I ever get is a "it's hard to pick up an agent that spoke to you technically"...one of the sales agents in the store said to me that I was never supposed to be paying for 2 contracts the one is supposed to be cancelled immediately..even with recieving my phone,I'm aware that I should have my I'd and copy of proof of residence when the phone is dropped off,I did not complete any of that documentation neither did I sign for the phone that was dropped off.i will advise anyone that I know to ever take a contract with Telkom,cause of the pathetic service!!!!
