Useless Vodacom staff

A whole month now trying to solve an issue ,their staff from collections dept (Julia and tsepho) give wrong info and make false arrangements ,their supervisors like Nomfundo totally useless ,and now the south coast reginal.i presume sthe kumalo even more useless ,false promises of getting back to me ,I still can't receive calls on my nr despite having made arrangements,so why must I stick to mine when you can't stick to yours ????totally useless and pathetic!
