Dischem rogues

On the 27/11/2018 i placed an online order with dis-chem, they called to tell me that the 1 item i ordered was not in stock & they would like to refund my money. I agreed & asked the lady if i should give her my banking details she said no she has it.Until today the 4/02/2019 nobody wants to help me ive called them over 6x they keep putting me on hold and then they tell me they will tell my “story” to the online manager & shell get back to me, nobody called me back nor have they given me my R175.00. For some of us thats alot of money & besides even if its R10.00 they have no right not to give it back. Please help!!!
