BILLING MESS

Good day, I've been trying for the last year to have my Vodacom account rectified, the account I have was a company contract, I've taken it over in my personal capacity, completed the required documents, amended bank details, however, the incorrect account is constantly debited, I've sent several emails I've attempted calling to have this rectified, I get transferred from person to person I now have lawyers calling me and yesterday I spoke to over 3 people and still did not get any assistance, my account is now at 11000 I don't know if this is cos they are terminating , I sent an email to the legal team and I still don't have any reply nor an automated response acknowledging that my email has been received, please advise how is this going to be rectified, how am I going to get compensated for this because this is not my fault and I've done my bit , I have the lawyers calling me, I have Vodacom sending me emails about my account but no one is assisting and i'm certainly not paying a lawyers bill especially when I am not at fault.
