I do not understand why I only have 750MB to use? Am I placed on the wrong plan?
As well as the 750MB of GPRS, does MyVodafone and1512 show that you have additional data? The data allowance for many of our plans is split in to 2 pieces, usually data and GPRS. The combination of these two should add to your total monthly allowance.
The current excess data charge on the $69 cap is $0.50/MB. This would mean, in your situation, that using 215MB more than you allowance would have yielded an additional charge of over $100. What does your bill actually say the excess $49 charge is for? Out handy Bill Explainer may assist you to work this out.
What date did you sign up for the contract? Your monthly allowances may vary from our current plans online, depending on when you singed up.
Let me know how you go. I will be able to provide further assistance once I have a bit more information.
