FNB just simply doesn't care

Poor service and very disappointed. I informed FNB of a missing payment on the 17th of August. I had informed them that I had accidentally used the branch code for the account number and I was informed that someone would attend to the matter and that it should be pretty simple to find the missing payment. Weeks pass by and no response. I follow up again and get told nothing has been done. I get told that I will receive an email with reference number and a response. Didn't receive any communication. I followed up again and on the 10th of September I get a reply from FNB that I should contact the recipient and try to resolve it with them. Obviously they hadn't listened as I had told them that I had mistakenly used the branch code as the account number thus the recipient didn't receive the funds. I then spoke with Siphesihle from the private clients service suite where I had informed them of what had happened. Again I was not listened to and was told to send the recipient the proof of payment. I then AGAIN explained that I had mistakenly used the branch code as the account number. I was then told they would need to log ANOTHER escalation even though one had been logged weeks ago? I was then told it would take another 22 DAYS. I informed Siphesihle that I was extremely dissatisfied with their service and would like to speak to someone higher up. I was told that the case was escalated to the team leader and that they would get back to me within 48 hours. This was on the 11th of September. Tomorrow will be the start of October and I have STILL not received any response. Worst service I have ever experienced.
