Management not talking to customers

Cell C no better than MTN the management of both company's do not take calls from customers and have built a brick wall around themselves called a call center. I traveled 20Km to a store to get advise only to be told that they cannot help me due to the contract that I have cannot accommodate the request this by the very person who sold me the contract it is also not stated in the leaflets of Cell C. The shop manager could not get a senior manager to speak to me and said I HAVE TO SPEAK TO THE CALL CENTER but the call centers have no authority so again we play the broken telephone game HOW CAN MANAGEMENT MANAGE IF THE DO NOT SPEAK TO CUSTOMERS?
