no contract activated

i am complaining on behalf of my sister Khadija Seedat. she had taken out a telkom mobile contract at istore in pavillion on the 18/08/2015. she has givent he iphone 6 and told that her contract will be activated the next day. her cell c prepaid number will be ported to telkom mobile contract.To date, the port to Telkom Mobile has not come through. Upon my initial query, it was discovered that since my account with Cell C reflected a credit balance, porting would be challenging. However, I was assured by the sales consultant that the port would go though within a day.Subsequently, on September 3rd, 2015
