I think GLA Inc Attorneys are the worst. They can't assist clients whatsoever. I called on the 8th April wanting a settlement letter for my two accounts with African bank. I held on the line for over 10mins I hung up then tried again same thing happens. You listen to music and nobody ever picks up! I then called the collections department for African bank spoke to Nonhlanhla who said she could not help because I had to speak to a manager for a settlement discount & there were no managers around. I then got hold of Shaun from GLA after sending an email and he gave me a settlement letter but the Account number for banking details was not there only the Account name. The bank couldn't take my deposit because of that when I called him there was no answer. So I had to google their banking details. I've fully paid the Credit card account, I sent emails to Caroline, Nicolene & Shaun (GLA) proof of payment and asked for a paid up letter till now I havent had any response from either of them. Please can someone assist & help me with a settlement discount for my othet account as I'm trying hard to pay these off since they were overdue after I lost my job last year. Please [Email Removed]
