FNB's inability to resolve query

Bought 1 Gig Data from online banking for my Cell C phone on 01 August. Never received the data as Cell C said my type of contract cannot buy top up data from 3rd party, only direct from them, hence FNB transaction should not have gone through. Reported the issue to FNB and went into FNB on Tuesday 04 August for follow up - REF Rv ********** 57424 - even got a follow up SMS stating "WE ARE ON TOP OF YOUR QUERTY, BUSY RESOLVING IT", but since then nothing. Everytime you phone you get someone else who need to follow up and get back to you, but no luck. Looks like FNB really want to lose our whole familie's business, including my husband and father's business accounts over their inability to resolve queries. Find them dishonest in their service commitment and feedback.
