Cell C Accounting Nightmare

I got an email stating I need to pay R907.01 where I already paid R939. 40 last month and where is my free 1 month promised to me. I have not received any feedback on this..

I AM FED UP WITH CELL C

Someone from Cell C phoned me as soon as I answered put the phone down immediately. That person is extremely rude.

If you do not fix my account before 5PM Tuesday 9th of April, I will be contacting my lawyer to handle this case further. As you were in breach of contract last month, as i am willing to give it one last shot.

This is request number 13 just for Cell C in the past 2 1/2 months
