Mercantile bank genius idea to change thier name

I opened up a Healthcare practice a month ago. I decided to go with mercantile bank since capetic has given me good service in the past. What a dangerous assumption I made. First off it took me 3 weeks to open as a sole prop because of the terrible service. Now that I can live with. It cost me 700 rand in courier fees to send my banking details to the relevant medical aids. This bank now decides to change its name 1 month later and now I have to update my banking info with all these medical aids again because capetic decided to be spontaneous. What kind of professional organization does this when they have loads of clients who run businesses that need to keep thier banking details accurate. How many people will this create headaches for. Don't go with this bank. You will regret it. I'll be changing banks thank you very much.
