Treasury Department

I've been banking with Mercantile Bank for about 3 years and trying to get hold of someone in the Treasury Department is near impossible. 10 different phone calls on morning of Wednesday 4 July 2018 I was not able to get past reception, I kept getting cut off. I am trying to query a "Password Charge" on my account which I have no knowledge of. The receptionist at Mercantile was of no assistance 10 calls later. I never got through to Treasury in the end.
