Terrible bank

For the 3rd time now, in one year only, money has gone missing out of my account. Turns out thy double debited card purchases that were made... I have contacted customer service but only get a response through an automated message. It is month end and bills need to be paid but mercantile bank decided they are going to take my money again!!!!! Highly pi**ed off!!!! It has been reimbursed the previous times but only after 14 days... This is ridiculous!!!! Is it their way of earning more interest on our money by forcing us to not use our hard earned money... They don't give us interest but we all know that banks make money off of our money!!!! I will close this account as soon as it is reversed....
