No Customer Service or regard for Customer situation

I wrote a bad review on FNB yesterday regarding declined transactions on my account (for no apparent reason - no one at FNB has been able to tell me why the transactions were declined in the first place) that has caused over R4000 on my account to get stuck in uncleared transactions. I have logged a complaints directly with FNB, I have submitted dispute forms via 3 different channels already, I have tried contacting them via phone countless times (from the USA on my account)... and, as a last resort, posted a bad review here yesterday. I got a quick response, got given a reference number ( ********** NF) and was told the matter has been escalated to Private Banking for investigation. Well, it should come as NO surprise that NO ONE from FNB has even tried to contact me since.. it has been more than a day later. I tried following up on all dispute form submissions via mail but only get automated systems responses - no human interaction what so ever. Even trying to follow up with their complaints department is met with an automated response and STILL no human feedback - I even tried calling and eventually dropped the call after 10 minutes being stuck in a queue waiting for an agent (just goes to show how many unhappy customers there are). This is absolutely ridiculous - I am being put in an impossible situation where I have been stuck without money in my account since Thursday last week because of something that FNB did wrong on my account, refuse to fix and refuse to take any responsibility for. The worst banking experience ever
