Scammed me of R300

Magoebaskloof hotel (not Magoebaskloof getaway) scammed me of R300. They double deducted for a massage. I forwarded proof of payment and bank statements to proof the double deduction but I was told they can't call me because they don't have airtime. I was assisted by Caroline, Vincent and Jadon but none of them has bothered to explain where the other R300 went to cos on my statement is reflected as Magoebaskloof hotel. They blocked both my husband and I's number because they don't want to refund me. Their contact number is 015 590 990. I am so ashamed of their criminal act
