TERRIBLE BILLING SERVICE

When I accepted my data contract from cell c they informed me that when my benefits are over it is an open line and charged accordingly I had agreed with them that a 50 rand cap should be put in place so that when my benefits are over I can use the open line to a maximum of 50 rand. I received a bill for next month for more than what the cap was supposed to be set at now they tell me its my fault cause I didn't realize within 3 months that their consultant did not set the cap. as a customer for the last five years with cell c I am disgusted with the treatment received you expect me to stick to the agreement but you cannot? you don't value customers and this is the last straw please get someone to call me to cancel all three contracts as I will not remain with a company that lacks ethics when dealing with customers. ref number ********** 935
