Standard bank appauling service.

I have been on holiday to ****et Thailand in June 2018. I now sit with a dilemma of my outstanding room deposit. Mr Kumar Lyander from the hotel queries why standard bank has deducted the entire holding deposit whereas they should only deduct room expenses at the end of the stay. I did speak to Lebo Monare from charge back escalations who made me fill out a dispute form but only to later inform me to go back to the hotel to resolve my issue. I was not given a explanation of why she could no longer help me. I am a standard bank customer for more than 25 years and to be brushed off like this is not acceptable. Further more being a customer of standard bank i have a right to know where my money went as the hotel insists the fault is with standard bank. My colleague who stayed with us banked with Ned bank and had no hassles what so ever. Only the room expenses was actually deducted from her account. At the end of the day I am missing money that is due to me. I would appreciate standard bank to help me get to the bottom of this.
