Absolutely pathetic & disgusting Customer Service

Intellicell had debited my bank account four times within 8 days (between the 22nd - 29th September) even though I only have 2 contracts with them - so basically they double debited my account. When I called them to notify them about it, their first response was - it does not reflect on our system so no that is not what happened. I have been calling them from the 2nd of October to get my refund back and up until today nobody can confirm to me if all my money that was debited extra is returned to me. All I am told is that they will take my number down and get someone to call me back within 10 mins and 2 weeks goes by and still no calls. If they are not promising to return my calls then they drop the calls. I have called them on numerous occasions - at first I was told that the compliant was not registered and they are not aware of the refund, then after about 8 days or so I was told that the refund request has been put through but they are not sure if it will be approved, then eventually today im told that it was paid out but then they are not sure as to how much. I have spoken to Desiree, Andile, Anila, Clara, Chanel...Clara the CS Center Supervisor told me that she will call me in 10 mins to confirm if it was the full/correct amount but instead 2 hours later she opted to go for lunch..desiree - after talking to her on numerous occasions since day 1, who promised to call back so many times, dropped the calls down on my ear so many times tells me that the entire accounts department closes the department down to go for lunch altogether so there is nobody that I can talk to - after my 3rd attempt and that is just for today alone. I called yet again and this time I got to speak to anila/andile (not sure if it is the same person) - tells me that she cannot give me her GM's name and that there is only 1 Manager who I can talk to but she is not in..Clara the supervisor is busy and it doesn't matter if I want to lay a complaint on Social Network I can go ahead as there is nothing they can do other than telling me that they will call me bac**** with my experience with them for the last 2 weeks of them telling me that they will call back and they didn't, do you honestly think that her word carries an weight????she dropped the call on me. I am tired and fed up of calling intellicell for my money. when we don't pay just 1 month we get calls upon calls upon calls for just 1 payment missed, yet here 4 debit orders taken out and absolutely pathetic customer service, attitude from these ppl. I do not want to talk to customer service agents or the supervisor as their telephone etiquette is absolutely disgusting!!!! I have wasted soooo much of my time and airtime just trying to establish if my refund request has been sorted out and when I can expect payment and still nothing. This is not my first time of such incidents occurring with intellicell. I had another similar incident in July as well.
