Stupid people who still need more training, cell c must close down

I am sick and tired of cell c customer service, in the stores and in their call center, I bought a phone by December 2015, signed the contract in one of their stores, no copy of the form I've signed was given to me, only the phone, first month deduction was correct , then after that they were doing the opposite deducting extra and give me lame explanations, so I decided to block them from deducting in my account, now they blacklisted me, I'm trying to get hold of them to pay up their amount that I'm owing, no one is picking up the phone, no one is responding to my emails, no one is giving me answers to my complains on their Facebook page, cell c must just close down, their full of sh***.....my number is ********** 847, and now I called their call center been transferred all around my call being dropped, at the end they gave me numbers that are not even working, m sick of you cell c , someone must call me or I will have to sue you for defaming my name, really now I'm sick, you never find customers who run after you to pay, but I'm trying to do good here and you spitting back on my face, I'm now tired of calling your credit line, you must get someone to call me with all the information that I need, how much I'm owing and how do I pay for the stupid phone that you wanted me to pay millions for it , I'll be expecting your call, my numbers are (personal number : ********** 847 work number : ********** ) , call me before my lawyers get involved
