Still No Feedback & Still getting Billed

10 days later I am still waiting for feedback, i had to call yesterday 2 of my 1st calls were disconnected... a guy answered & hung up on me after realizing that I am calling too often for something he cannot resolve, the 3rd 1 went through and something that was supposed to be done on the 8th of Dec it was only done yesterday after demanding to speak to a supervisor that's when she cancelled my contract but I'm getting calls from your sales guys trying to upgrade my contract, really??? After all this ****y service on top of that i get an invoice this morning & i have to pay again for for a contract i cancelled in Dec... After soo many years with Cell C I'm soo disappointed
