FNB allowed an amount to be deducted from CT Card after urgent appeal of ***** transaction

Sunday evening I made n online purchase for R775. Monday (30/8) I woke up to a message from FNB ***** department stating my card is blocked - looks like ********** transaction. I went into my account and noticed that the place I placed an online order for tried to take an amount of R914.50 (the amount the ***** department picked up). I then checked my account and saw that the "online company took R813.75 instead of R775). This R813.75 was still in pending. Immediately I realised that this online company is a *****. I contacted FNB via phone. They cancelled my CT Card and then sent me a form to fill out to get the R813.75 amount back. I still said to the lady they must stop it it is still in pending. She said NO THEY can't do it. I completed the form. Sent it to the address given and to date I heard nothing. This morning I noticed the R813.75 went from pending to paid. How on earth. FNB I want the money back. This is not the service you would expect from your bank. Carien Bosman ***
