fnb is completely useless

***** was done on my account in February. I went into the branch on the 12th of march, cancelled my card and they said I must fill out a form which I did and then did it again the 18th March to which I got a reference number and was told it would take 30 days, it is now over 30 days so I went into Eastland mall branch again today to find out what is happening to be told it takes 30 working days which is a lie as my sms and system st fnb says 30 days for them to call the manager who says all they can do is lay a complaint. This is completely unacceptable, you guys are useless and have no customer service standards st all.
