Worst banking experience.

Good morning,I received the worst service ever after trying for weeks to open a business bank account with Mercantile Bank .I was in communication with Dumisani Mngomezulu my supposed personal banker ,after numerous unanswered emails and phone calls ,I decided to terminate the entire process and will be looking for service from another bank , needless to say that he's response was so swift I can't help but think that if he responded so swiftly on previous emails and phone calls then perhaps I would not have waisted my time and energy and would be having a business bank account .It is clear Mercantile Bank I not serious about business.
