Stole from me

I went to Liefde by die dam in Aug. I put R200 on my cashless wristband. I bought 2 waters and 1 brutal friut. When it was time to refund me the rest the said they are only going to refund me R3. I contacted them immediately. They said the rest will be paid in between 7 to 14 working days. It's been 16 days now. Still nothing. Contacted them again and now they know nothing about it. They are *****ing money. Be careful
