Technical fault duplicates Checkers purchases

<p>Who is at fault... Checkers or FNB? 3 times in the last month, I've used my FNB Credit Card at Checkers (2 different stores) and this is what has happened: The amount is deducted off of my account and then a "duplicate" of the amount is put on hold. What this means, is that my shop ostensibly costs double until the duplication is taken off of being on hold. This reduces my available credit. This is absolutely unacceptable! I don't budget for this which means that when I need to put in fuel in my car, I am unable to due to a technical issue either on FNB or Checkers side. Checkers says it is FNB. FNB does not refute this claim!</p>
