Money not returned to my account

Good day I am getting tired of what stand bank is doing to me. I played lotto last week and the system was not working and the money was reversed back but didn’t reflect into my account. Today I am trying to buy electricity and the system is not working. I got an sms saying the money is reversed but still is not reflecting. If this is not sorted I am closing this account. I work hard for my money for standard bank to take it and not return it. Please sort this out.
