Terrible service! No assistance when so desperately needed!

Today i made an online purchase on a website only to have done some investigation and find out that it is a **** website!!! When i called Fnb ,they told me that the funds have not left my account yet and that it was pending. However they could not stop the payment from being made!! And sent me a reversal form which will only be attendd to in 5 days!!! Absolutely disgusting that they could not help me anymore then this! And to top it all off when i called the ***** department they didn't even suggest i cancel my card! I clicked in the end that i should do that to be safe! Could have lost even more money! You would think as a ***** department they would immediately suggest these things to their customers! Definitely thinking of switching banks!
