Stuck and Frustrated with FNB

I tried to buy a product online and FNB mistook it for a ********** transaction and blocked my debit card, which is a business card. It has been a week now and I've tried everything to get the card unblocked but to no avail. The *****line number does not appear to work. Trying to get help from the business line has seen me transferred from one person to the next. I've personally spent about one and a half hours on my cell phone holding and being transferred around. One person suggested I go to the branch where I spent another one and half hours and left with no joy. I went home to call the number given to me from the branch and was transferred again and then just abruptly cut off. Needless to say that we have been unable to do any transactions with our card. I stuck and frustrated. I think all that remains is to take the money out of FNB and place it in a bank that actually functions.
