********** upgrades opened on my account

Vodacom service as a whole sucks. I discovered that there were ********** upgrades opened on my account. I submitted all the support required by Vodacom. I was informed that I will be credited and the amounts refunded to me. I have been following up with Vodacom but no one can inform me when the amount will be refunded. I have been given the run around. When I logged into my account I see that instead of credit notes been passed, I have now been incorrectly invoiced for more handsets. The amounts are way in excess of my salary. It seems like they will debit my account for theses amounts taking all the money out of my account. Once this happens, I will not have any money to pay for my bond, car, school fees and my son's medical aid which is very essential as he has a heart condition. Thanks Vodacom for messing this up!!!
