Airtime purchased and not received

Last night I purchased R150 airtime and R155 via FNB online banking. I received confirmations that these amounts have come off my account but they are not reflecting on my airtime/date balance. I've double checked that the purchases went off and that they were for the right cellphone number and network. <br> <br> Purchase references<br> - Data - *** - Vat Reference - Cell C *** <br> - Airtime - *** - Vat Reference - Cell C *** <br> <br> I'm not sure how much of this is an issue with FNB vs. Cell C - but I really would like a solution to this as soon as possible - please get back to me with a way forward.
