Worst service ever from FNB *****

On the 23rd of November I had a ********** online transaction that went through from my account, and I immediately canceled my card and reported the transaction at fnb ***** then I was refunded. On the 27th of November the transaction went through again yet my card was already canceled i called fnb again and I was transfered from one department to another till today I haven't been refunded I'm disappointed with the service I've received from FNB I have used so much airtime and nobody wants to help me their service is very poor.
