Cell c pathetic

Cell c is pathetic. They deactivated my line because they moved over to a new system and did not allocate all my payments made, which have always been up to date since I use my fibre for work purposes. They then claim I owe them money and deactivated my line. The agents who helped did not do anything with my proof of payments shared. So now they want me to go reapply for new service. Absolutely pathetic. Wake up cell c. Especially with customers who are up to date with payments but you can't get it right because of your incompetency
