incorrectly charged

I have noticed that 3 debit card transactions has gone threw as international transaction when purchasing local. i contacted standard bank customer care to sort it out this was 18 January 2015. i then received a SMS 19 January 2015 that the dispute was unsuccessful. i contact them again they then advised me to go to my home branch. I went to standard bank in Alberton on friday the 6th of Feb. they said they will send me an sms with a reference number and a consultant will be in contact with. i have not had any sms or call from standard bank. I want this resolved asap. i dont understand why i have to go threw all this trouble to get some answers. phone calls, visits to the branch!!!! WHY??? R105.00 is R105.00 its still my money!!
