3 months ******ion of money whereas I've cancelled the contracts in time

I have been having contracta with cell c for 10-15 years about 3. Last year April the 15th before my upgrade date I cancelled the two to be on prepaid, one to downgrade just receive data. On the 27th April I followed only to find out my request wasnt action as per request. Again on the 09th May I followed up. I went to Oakfield Cell C seeking for help, it took over 3 months for them to resolve this. I was billed around R3000 which I paid though OT was not my fault because our 3 lines haven't been working during that 4 months. Then it was settled that no more billing and I'd only be billed R99 for 5GIG and 5GIG nite. Came end of August my bill was about R4000 a nd went to see the manager at Cell Task field who help me with this and we even spoke to the Cell C agent at account queries when I paid that money..And promised us this was resolved. The manager paid plus minus R700 from his pocket hoping to claim it from the company which he never got it back.. Now all the numbers haven't been working since Apri.1. *** mine 2. *** my sister's 3. *** my daughter's. Cell C treated me unfaily and unreasonable, denying to take accountability. And this was ******ion, worst if all for their loyal customer that would be playing about R3000 a month. I have received calls from many of Cell C agent about the account. When I explain o them what really happen ,they must look into it, all of them I mean all, they'd just drop the phone on my ears. Now, they have handed me to the attorney's, for what? Running away from your responsibility and made us suffer even lost so much money for something that wasn't my fault.i have been paying my contract up to date forbthe past 15 years. I am very disappointed how the head officer handle this.
