Poor Customer Service, FRASTRATED

The Worst part is that though the payment has been done fully and in store everyone says so since November, the calls go through after one hour, no one is assisting and there is a hold that only Cell C can resolve, and they are willingly not doing do. Experian Credit Check has blocked every single credit and it leaves me phoneless and very frustrated. The highest regret I ever have was to take the contract in the first place with Cell C. I need either an Upgrade or New Phone for the Insurance paid!! Cell C can't take a hard earned cash for the poor and get away with it. I need justice!!!!
