Pathetic service beyond comprehension from FNB Forex department

I have been trying to get a Forex payment that was made on 10 January 2020 releases into my business account for the last two weeks. After 15 calls and several emails I am getting no response - I guess sitting on the money and keeping the interest is good practice FNB? I send emails to the correct addresses, follow up emails, not a single response! I phone the Forex line several times a day, every time the person on the end of the line promises to get back to me, but never does. This service is pathetic beyond comprehension! Perhaps opening a case of theft with SAPS will get them to move?
