Unallocated account

I have been strugling with an unallocated payment on my account since june 22. I made a payment of 310 rands which was not allocated to my account. I have since sent several emails with proof attached im not getting any assistance. I instead wake up to a disconnected service every week but my issue is not getting resolved. How much money should i spend on calls before i have peace of mind. Is there anywhere i can lodge a complain about this issue. Can it really take you guys 6 months to allocate a payment. I have been paying the premiums for five months and that maybe the reason why you are not attending this case. I decided this months not to pay the whole premium but that immediately attended by disconnecting my service. Can you allocate my payment pls. Smartcard ***.
