Dont trust the bank

Hi. Tell me. How can you trust a bank who doesnt have your back? You know the spam callers? They phone and very convincingly get you to agree to pay for something you dont actually want or need. So just to get rid of them I agree. But the second the call ends I know I dont need this or I cannot afford this. So when the debi check messages comes through I DECLINE. Thinking that they wont be able to take the money from my account. Cause they made sure they send the debi check the second the call ends. Ok great. Debi check has been DECLINED. And then Surprise!!! There goes a debi check off of your account. When i least acpect it and did not provided for it. When you go to the bank they say sorry we cannot stop or reverse debi checks. Like whaaaat? How did it went through in the first place??? The BANK cannot assist you or help you in this regard. I am not a rude person but when im ****ed im ****ed for a reason. And im ****ed. People taking money from my account without permission. I am allowed to change my mind at number 99. But Noooo not even the Bank has your back when you decide to change your mind. Oh and the best part the bank cannot help me to open another account for all the ***** that is happening without permission on my current account. Thank a lot hey.
