After service terrible, not interested to assist

Hi, we went to Medicare Vodacom to take out a new contract, at first because we weren't helped we complained and the Manager decided to assist . She assisted us but after we took the contract all the issues started. I am battling now for almost 3 weeks for them to assist. I am a pensioner, 2 contracts were given to me, the contract was not in my name. Now when I ask for assistance they keep saying they will get back to me but no one does, when my daughter contacted Vodacom they have nothing on record to say the accounts need to be changed etc... I gave then time but now it's really disappointing how they dealing with my account.
