FNB CALL CENTER

I paid a settlement on my loan at FNB and emailed the proof of payment as stipulated on the 12th of July 2022. To date my loan still reflects as unpaid. I've spent over 300 min on the phone with them over the tast few days trying to find a answer. All I get is transfered from one department to the other. Or my call just gets cut. I wouldn't recommend that anyone banks with fnb. There call center is a waste of time and money
