Still waiting for the promised itemised statement

I took out a new contract a few months ago and was shocked at the first bill. They admitted that I'd been incorrectly charged twice for 300 MB of data, which should have been included in the monthly fee. I seem finally to have been given some credit, but I'm not sure what it's for.<br> <br> I'm also still waiting for the itemised list of calls that allegedly put me R145 over my 100 free minutes that first month. I have been charged R18 for this bill twice. I eventually discovered they had a typo in my email address, so they said they'd resend it and reverse one of the charges. I waited for over a month before calling again on Sunday. I was again promised the itemised account, and again it hasn't arrived.<br> <br> What's so difficult about sending me my list of calls, and a proper explanation of what I've been credited for?!<br> <br>
