No service

I have two contracts on my name and had to make a manual payment this month for the first time since I entered into these contracts. I called the customer service to obtain the banking details and asked the representative what must i use as their reference in respect of both these accounts. I was advised that I must use my cell number as I am the account holder. I made payment on 4/2/15 in the sum of R555.41.On 10/02/2015 I was advised by the person using my second contract that his number was out of service due to non-payment. I phoned customer service again and instructed the consultant that R206.01 was to be allocated to my account and R349.00 to the other contract. Needless to say this did not happen.On the 11/02/2015 the person using the second account advised me that I must contact customer service. I again called them and was then advised that i cannot speak to the accounts department but that a note would be made. The second contract has now been suspended and shows it as being in arrears. Why? Despite numerous phone calls, there has been no progress or a even phone call from Cell C while in the meantime the second contract is suspended? ***.Simple instruction?
