R150 out of my account

R150 was transferred out of my account of which I don't know what is it for including charges of R31.50 .On the 19th January 2016 I received an sms then immediately I phoned standardbank call centre then they couldn't assist me they said I must phone recovery dept with tel no *** I phoned recovery dept then they said they can't see anything from their system then they referred me to branch when I arrive at the bank I had to call again inside the branch. I couldn't get help until today since I've been phoning this are the reference numbers ( ***, *** and *** and other which I didn't record) I was provided with everytime I phone coz you find different consultant each time when your phone and I keep giving different stories about money. I was transferred to all the dept of atandardbank but even today I couldn't get help. ***** department, legal department u name then so I think hello peter is my last hope. if I don't get solution I will need to change the bank, I'm so disappointed and angry for more than 10 years banking with standardbank I never get so frustrated. I losing a lot because of R181.50 I'm using fuel to travel to the bank & airtime to phone.
