Credits not passed now account has been suspended

Since Altech Autopage took over the Cell C accounts from Nashua Mobile my account has been in a mess. My number in question is ***. I had upgraded with Nashua in October 2014. In November all the contracts were ceded to Altech. With my previous contract before my upgrade i was paying a device charge of R70 for the phone or either the Xbox that came with the contract. Nashua informed me that October would be the last i would pay for R70. The new device charges would be R50 for the Blackberry on the upgrade. Altech has been charging me R70 and R50 amounting to R105 every month. They were charging me for BIS, Itemised billing since they took over and i never enjoyed the benefits. In January i queried this with their call centre and then trouble tickets were opened 565825, 565829, 565833, 565846. All the credits were never passed. During March i visited their office in Midrand at least 6 times liaising with a Merchant Govender and a Thuletu Mashibini. I called them but no responses from their calls and no email responses. Nor do i get my bill via email as request. I am still waiting for a recon to see the credit before i will make payment. This is so very bad customer experien
