FNB soliciting bank charges

Soliciting bank charges for transactions is just another kettle of fish. This is the third time this year, I’ve gone through this issue with FNB, but now you’ve taken it to a whole new level. I’ve purchased goods online and the funds came off my account immediately. A few days later, FNB put through two charges on my account R600 and made it seem like I had paid for those transactions. When I queried it and asked them to reverse it, they insisted that was charges for a transaction that I had paid for, but when the merchant banked the transaction there weren’t enough funds in my account. Am I supposed to pay for a transaction and then keep money in my account for the transaction to be debited again? Are you guys crazy??? Then, to add insult to injury, they debited my account with a further R150 as an ‘honouring fee’? Have you guys lost the plot. I have to say, R750 for for fees that are not mine to keep, is solicitation! You guys will not retain me as a customer. People out there need to know about how you handle business after chatting to too many of your bankers and phoning in to resolve this! No resolution in sight
