Unhappy

I have been a customer with Absa bank for more than ten years but I must admit that i'm very unhappy .Every time i withdraw money specially during month ends I receive sms 's with the amount of money I have left in my bank which is correct to my knowledge, but when I go to the ATM to withdraw than the money is short every single time. Its either you guys double charge me on bank charges or you letting certain creditors double charge me which does not reflect on my statement. And this has been happening for quite a long time now I was once charge R1000.00 on bank charges for my check account which I closed as well..Every single time I go to your branches nobody ever helps me to my satisfaction .I'm so disgusted after I done all I had to do yesterday knowing I had money in my account only to find out this morning that I had short money again after you send me another SMS stating this is what I had left in my account only to find out that it was not true. I'm really unhappy and I plan to be moving my account to another bank that would not rob me of my hard earned money.
