Migration Overcharge

Since Migrating from Nashua Mobile to Vodacom I have had nothing but problems. I have not been sent my invoices unless I go into the Hillcrest branch and request it. I have to guess how much to pay.<br> This month I received a statement claiming I owe R8000 (normally less that R2000 pm) <br> On going through to Hillcrest query it, I had to stand in a queue for over half an hour,(this is very normal at Hillcrest branch) and finally I sat with a consultant for another 10 to 15 minutes only to be told that the problem could not be dealt with by him, and that I should phone a few numbers he wrote down. (further expenses to me)<br> He claims that my contract with Nashua Mobile for my 2x 2 gigs data was uncapped. My contract with Nashua mobile was most certainly capped and when the data ran out I used to top up. The odd thing is that they do cut me off when I reach my 2 gigs so how can it be uncapped?<br> The consultant claims to NOT be able to get a copy of the Nashua Mobile contract as they have now closed and that I will have to approach the legal department.
