Thanks for providing the details via PM, @6863166. We had a look at your account and it appears that the reason why you are unable to call is due to payment issue.
The payment is still in progress and please be advised that it will take 3-4 working days for the payment to be posted based on the type of payment method set on your account.
Im sorry but than answer makes no sense. Since the money was debited the 13/11 (and it the 6th debit not the first one!) ..... 6 in 5 months which also would like to be explained.
TPG is a prepaid service, which means that we charge 7 days in advance before the start of the next billing cycle as part of our billing system automation.
By operating this way we are able to keep costs down to continue offering the best value deals possible to our customers.
We are expecting for your payment to be posted either tomorrow or the 19th of November.
