Avoid Cell-C upgrades like it is a plague!!

One of my contracts with the mentioned Service Provider was available for upgrade for the better part of a year. Towards the end of last year, I decided to make use of the offer which was almost at the point of harassment. The new instrument was duly delivered two days later, but only a model number was supp****. Since I requested specific details and specifications during the upgrade conversation, and I was not able to verify that the device comp**** with my request by only looking at the model number, I repeatedly called the Cell C customer service number. This as it turns out, is a waste of good and valuable time. Here is the warning to any potential future victim's. NEVER EVER accommodate a telephonic conversation with a Cell C sales representative, they lie and will tell you anything you want to hear just to get the deal completed. As it is within my rights, I rejected the upgrade in writing less than a week from taking the call. Cell C acknowledged the cancellation in writing, yet they still debit my bank for the upgrade. Again, I notified the company in writing to which I received a response yet again, but no action is taken. In spite of the written cancellations, I must have spent at least two hours in the maze of departments telephonically. Once a service representative takes the call an ID confirmation is done, this takes forever and is super annoying but necessary I suppose. You then get to tell the story, only to be told you are at the wrong department and should actually speak to so and such. The call is then transferred and we start again with the ID confirmation, guess what - you guessed it - you are at the wrong department again and should speak with somebody else. After the fifth transfer, my patience is drawing short and I insist on the person to take action, this is usually where the call is terminated. Beware, this is a new strategy for nothing to happen - don't fall victim to the ****. I have a brand new instrument, sealed in the courier bag as it was delivered. I will not open it - the upgrade was rejected. Cell C is ignoring my calls to collect, the local store has packed up and left town, business seems to be getting shady. I think my only way to speak to somebody that actually works for Cell C is to cut off the money supply?
