Forex department USELESS

I emailed Capitec about an international transfer to my account as I work abroad now. I needed to send my invoice for my salary and was met with silence. I then had to get a family member to phone them and find out what needs to be written on my invoice in order for it to get cleared without me having to telephonically clear it (as I’m abroad). I was given three different methods on three different occasions meanwhile my original email had not been answered. I then sent my invoice on the advice from one of the Capitec agents, only to find out it was wrong and I needed to fill out a form. I then completed the form and sent it to the forex department. No acknowledgment that the doc was received and no responses to my other four emails. This is absolutely the worst service I’ve received from any bank. Because of their incompetence my salary has been delayed and I still have not received a response to all my emails. What the hell is going on?? It’s not like Capitec has millions of customers trying to receive international payments. I have no idea why they cannot help me. Poor service delivery from a supposed tech savvy bank. I will be changing banks when I get back to SA
