The fact that Cell C can't figure out why their system is doing something illogical is not my problem to fix.

For two months in a row I have lodged an issue with the Cell C call centre regarding the fact that my invoice contains incorrect information. The first month they assured me that the following invoice would be correct, and this second time they kept trying to put the blame on me... when I opened the contract I gave all my current and updated details, including document proof such as my ID, which the consultant duly copied for their records - I have no control over why your system reflects the correct details but the invoice doesn't. They kept telling me they can't do anything, and eventually hung up. In future I will make sure that the first thing I do is get the call centre agent's full name at the beginning of the call so that I can report them for unprofessionalism and rudeness.
