Cell c de*****ing customers

Cell c has been over-changing me for the past 3 months, and when you inquire and or dispute you are sent from pillar to post. C ell c has been de*****ing customers when it comes to data usage. You will be charged in Rands while you still have data. Asked Cell c to send me a copy of my contract with the clause that says i'll be charged in Rand while i still have data when i visit any sites and was told that the was no such a clause, you will only be charged if you are out of data (out of bundle) but this is not the case. several calls have been logged for usage validation and all are closed with a inefficient resolution. Cell c has no shame. you will be given one supervisor after another without any assistance.
