Poor service ***** dept STD bank

STD ***** departement decided unilaterally to block my accounts. Why I enquired they said they thought there was ***** on my account. We went thru all the transactions which I did and knew of andcthey said they will remove the block. I wanted to know from them why they did not speak to me first and got no answer. Apparently I didnot answer my phone while I was working. Unblocking worked for one day only. I went to the bankbranch and got a new card. It worked for 24hrs and then they blocked it. As a result I cannot transact at all, nor pay anything. Multiple attempts to explain and ask to unblock nothing happened. They are quick to block you for your owm transactions, but if there is real ***** they dont pick it up or it is not their problem!!! I have been a client since1998 and was never treated like this. I am furious ans disappointed. This is only the ***** departement. My branch is wonderful and do their best.
