Ex Nashua Mobile client: 860% increase of account

Has been a Nashua Mobile client since 2003 until all contracts reverted back to the networks. I have two Vodacom data contracts with two data cards each ( a total of four Vodacom data cards) and one MTN contract (two numbers) <br> <br> My instructions with Nashua Mobile were that all four data cards should softlock once data has been depleted and only unlocked on my instruction. I noticed a significant increase in my monthly billing since the move to the networks. I then established that Vodacom has removed the softlock instruction and increased the call limites for each card to over R1,000 (unaware of this I never realised when the data was been depleted). <br> <br> On only one of the contracts the average monthly data costs amounted to R473.05 over the past 9 months since the moved to Vodacom, compared to the last 6 months' Nashua Mobile invoices on the same contract averaging a monthly cost of R55.04 - an 860% increase in the invoiced amount.<br> <br> Called the customer line repeatedly. I was informed it would be investigated, but no feedback since. I have repeatedly tried to contact their customer service unsuccessfully. This matter is now being refered to the Consumer Commission.
