***** on my account

I've reported what amounts to ***** to FNB so many times in the last few weeks and have gotten no positive responses or even care from anyone there. When I've requested 2 refunds from Takealot, both times my account was charged (using virtual cards) and I've had pending transactions on there ever since, the first one was fixed, but it still did not properly fix my balance on my account and as a result, there is an outstanding amount of R984 for card authorization that no one can tell me what its for because no one can see the transactions, in addition, there is still a pending Takealot transaction that has charged my account. FNB, this is a very serious matter because it is essentially *****, CAN SOMEONE IN THIS BANK PLEASE DO THEIR JOB AND RESOLVE THIS ISSUE ASAP...
