What exactly did you do?
Just top up your credit balance?
Or top up and then buy membership or add-ons?
Describe the exacy steps that you took.
How much did you top up by?
Dial *100# and hit call/send to get your cash credit balance - what does it return?
Does this reflect the amount of your recent topup (assuming it wasn't subsequently used to buy membership/add-ons)?
What does your online account say about your membership status, expiry date and calls/texts/data/cash credit balances?
