Problem porting number from Cell C

Can someone at Cell C tech,please help me port my number away from Cell C. I was impressed with Cell C sponsoring a Surf Swim race at Durban Surf, so I decided to open a new contract with Cell C to show my appreciation. Big mistake. It took one day to port to Cell C and then I started dropping calls at my home/work place. I was told at purchase that they have a 7 day no questions asked return policy..... Not true, So day 2 of contract I return to Westville Mall Cell C and explain the dropped calls. They send complaint to Tech who take 2 weeks to tell me that I unfortunately live/work approximately 2 or more km from a Cell C tower (poor reception) and I can cancel my contract. So I agree to pay for my phone in full and one month contract so my number can return to "pay as you go" and I can port to a network that has good coverage in my area. So I decide to port to Telkom but 3 x porting attempts and Cell C still have control of my number. I have phoned Cell C 3 or 4 times and they tell me that the problem is with Telkom and my number is ready to port. So I have opened a case number with Telkom as to why my number won't port. Cell C Tech are amendment that problem is from TELKOM. Cell C please release my number so that I can port. I'm told that once you port that they hold onto your number for 3 months --apparently all networks do that.
