Appalling Service from FNB - Erroneous Declined Purchases

There are 17 declined purchase charges of R8,50 each on my FNB Card between 21 May and 06 June, even though this card was not used at all for any transactions during this period. On 31 May I was told by the FNB Call Centre consultant that there is a system problem and she assured me the erroneous charges would be reversed in 2 to 3 days. I am still waiting. My account is still being debited daily with these fees. Appalling service from FNB!
