No Service

I have been to the store (carnival mall ) on 4 different occasions and with NO help from them. I bought and paid for a 1 Gig data bundle for my wifi when it ran out of data in the last week of November. I loaded the bundle and it showed my account was credited with the data. After the device was still not working as it kept on saying I am out of data when I connect I returned to the store with my device and they looked at it and my account and assured me that it was sorted out and working. But when I returned home it said the same thing. After the 1st of the month vodacom debited my account and the connection said the same thing. I returned to the store again with the device and after 30min they again assured me everything was in order. By the 5th the account was still not on I phoned the store and the lady at the store said they are going to fix it and phone me back. They never phoned back and I am not getting any assistance from them. This is the worse service I have ever received from a \service"provider<br> I am considering cancelling my 4 contracts I have with the provider and moving to someone else"""
