Can't cancel contracts and migrate contracts

I have phoned, emailed, gone to branches and done all the paperwork and still they have not migrated or cancelled my contracts. When you phone it's a different story every time. You ask to speak to a manager and you never hear back or they are always in a meeting. Just want to cancel my contracts because of the appalling service. Not knowing their jobs. Emailing retention department is pointless. Overall bad service and clueless employees. Very annoying<br> Being billed for contracts that have been cancelled aswell. Might aswell change networks and get away from MTN. Worst network ever<br>
