DELAYED BANKING BY MERCHANT

I made groceries from Checkers Hyper on 30 October 2017 and received an sms notification that the amount has been deducted from my own account. I then again received an sms notification on the 20th December 2017 stating that an amount of R2191.12 has been paid from my account following a transcation from checkers hyper eastgate on the 19th December 2017. Off course I was concerned as I am currently in the Eastern Cape and made no such purchase. I enquired from FNB and was advised that Checkers as tbe merchant had banked this amount late. Due to their delay I suffered an inconvenience as this amount was not budgeted for. This experience has never occurred before. Highly upset for both FNB and Checkers Hyper incompetence!
