Incorrect Data / Bad Service

Issue at hand:<br> <br> from 1-3 August My old contract data was meant to be used and from the 4th of August my new contract fell into place, however instead of using my old data(1-3), they took almost All 100mg of my new data(from 4th) on my NEW contract, at this stage i had not used any data for that specific day (the 4th) meaning all 100 mb of my data should of still been on my phone because my new contract ONLY took place on the 4th. <br> <br> I contacted Cell C Sandown (4 aug) and spoke to 2 men, 1 is shane, and the other is Mathew (or something like that) He now no longer works there and moved to Century City, he didn't bother to sort out his customers issues.<br> <br> Last week I phoned to talk to Shane(train) - He told the other man in the store that it was Mathew (whoever he is) job to get back to me, But i was NEVER contacted.<br> <br> I am sitting now 2 weeks later, without data, being charged extra for an issue cell c should of sorted out. I'm actually so upset with the service, they used to be so good but clearly going down hill like the rest of SA. No one answers the phones (century city) no one is getting back to me, no one is sorting out my data, and in the mean time i am being charged extra.HELP
