FNB Unresponsive to the theft of my funds. Their Virtual Card is unsafe. And they don't care.

It's now been 75 days since the 16th September, when I reported irregular transactions from my account. Still no resolution, no refund. Here's what happened. An entity purporting to be my fibre service provider is sending me something and I need to pay R35,34 for the courier. Being cautious, I furnish them with details of only my Virtual Card. The FNB safety promise on Virtual Cards is that it is safe as "The CVV Expires in 1 hour". It should thus be impossible for a merchant to keep coming back for more payments as ********** do. Hours after the transaction, this entity debited another R89,30. Three days later they debited another R394,72, and then a further R772,11 on the same day. Quickly, I went to report this to the Fourways Branch even before the money had been taken off my account. FNB could have blocked it. They did not. The matter was reported to the Card department. I followed up after about 10 days, no response had been received. The consultant escalated it to the Care department which promises to call within 48 hours. Nothing happened. After a further 2 weeks I was referred to the ***** Department where a new process was started. Later the ***** Department referred me back to the Card Department. Today is the 29th November, I'm still being tossed from pillar to post, and I'm still waiting for my money. To be clear, I've been an FNB customer since 1994. I've been let down by their Virtual Card system. It does not offer the security it promises, so my money got ******. All the evidence is on their system. I'm not part of that system nor of the bank. All that should have happened is that they refund me my money and proceed to investigate their system to their heart's content. Yesterday I spoke to Nonyameko at their ***** call centre as well as to the branch operations manager Mr Derrick Singh. They promised that I will be reunited with my money within 24 hours, which has not happened. This is a callous, non-caring bank that bullies its customers. And their Virtual Card does not work.
