Poor customer service

I’ve been trying to get a settlement letter from Wesbank for over a week now with no luck. I spoke to someone that referred me to Boitumelo, I left messages for her, she never called back. I finally got hold of her she said I’ll receive an email in 48hers. I still haven’t received it. I called yesterday and I spoke to some lady who didn’t know anything. I’m still waiting today. The service is really poor and people don’t do their jobs.
