Poot service from standard bank

on the 4th of july there was a *****ulent activity that took place in my account,I immediately went to standard bank sun city branch,my card was immediately blocked and ***** case was opened,i was even given a case number,i was told that the matter will be solved in 7 days if not i should call them which i did after 8 days but no one was picking up.I then went to standard bank mooiriver branch,they also tried calling that number but still no one picked up even the following day the same thing happened,they then told me that they will call me as soon as they get the response but till today.According to the consultant that was assisting me at moooriver told me that i was supposed to get my money after 48 hours.I decided to google the other ***** department number of standard bank on the 19th,the person who was assisting me told me that my case has been elevated and will get my money yesterday which didn't happen,i called again today and i was told the same story i heard of the 19th that they are elevating my case.I need assistance
