Account locked

I'm so angry and disappointed with standard bank.. 2 months ago i went to withdraw money and it didn't come out, i received a slip saying i should visit the nearest bank. I went there and they told me i need to provide them with my proof of address because they did not see it on the system, they did not even let me know what's happening or what is it that i should bring to the branch. after that they re opened my account.. 3 weeks back i went to the bank again to withdraw and the same thing happened, my money was locked i don't know for what. i went to carnal walk and found a lady who was rude and told me that it was locked because i have to increase my monthly limit to 10000.. i asked her why don't standard bank send me notification on what's happening with my account instead of them locking my money whenever they feel like. they re opened it again and now to my surprise my account is locked and I don't know for what.. I'm extremely angry at the moment i don't want anything to do with standard bank, i just wish they can open my account and i can take my money to somewhere else, i can't afford to ask for days at work and go to standard bank every time they get bored and lock acc
