PATHETIC SERVICE

I sent a message to the FNB self service portal, querying a negative balance that i found on my account this morning… the clarity that i received is that “funds were reserved” when i made a purchase, however the money left my account when i made the purchase… so i’m now expected to make provision of the negative balance that my account is on, how? and every week i have to pay some sort of money towards my negative bank balance and it’s for this reason that i never want money inside my main FNB account
