Putrid Customer Service

I settled my contract with Cell C after contacting them twice. I have sent the proof of payment or the following departments: Queries, collections, proof of payment and RMCS, there is just no response. Two case numbers later *** and *** and still no response. Cellc contract department cannot even find any information on these case numbers This is really pathetic, I have called 7 times and still being sent from pillar to post. I want an answer Cellc before 2022 because as your customer I have now done my part and recieved pathetic service in return.
