unacceptable

i continuously experience this i have called the contact center numerous times regarding this and i was told they cannot do anything

when i swipe my card at any garage it says approved however funds are not removed from my account its stays there for like 5 days and then out of no where money goes out my account leaving my account in a negative

i was told that i should focus available balance and not current balance i done that still same thing keep happening this is not acceptable for instance i had filled fuel on the 21/03/2018 i swiped my card and this was approved i had 241 in my account all debit order we as i get paid month end i fill 100 fuel leaving me with 141 in my account as the cheque account im using i have free unlimited swiping i never spent any other money on that day however when i check my account nothing has gone of

i left the money in my account on so still with the available balance" on my account i dont my own calculation i filled fuel again but this time on the 24/03/2018 this too was approved but yet again no money was taken from my account so according to well my calculations i should be left with 50 buck however my account is in a negative when queried im told that i am at fault this just doesn't make sense bear in mind this has been going on for a very long time im tired of being blamed or told that im at fault this needs to stop as of today or nedbank you can go ahead and close my account i can move my business elsewhere
