A day full of stress from Aronia Day Spa

I was given a voucher for Aronia for my birthday. In having my home painted, I have misplaced my voucher. I called Aronia to ask them to trace the voucher. I had the name of the person who gave it to me, their cell number, bank details, date of purchase, and the amount paid. They said they would call me back, but didn't bother. When I called back I had the most illogical and rude conversation with a person who kept interrupting me. All she could say was that I needed the voucher to prove I had the voucher. She asked what the voucher number was, and I explained I couldn't give that to her as that was on the misplaced voucher. She then asked if I could get the person who had purchased it to call and give the voucher number to them. No amount of explaining could clarify that I don't have the voucher or the number. I was then told to send them a WhatsApp, which could be shown to the manager, despite my having called twice and explained my problem to 3 different people. Even if I find my voucher, I won't be coming to your spa. You turned a beautiful, thoughtful gift into something so unpleasant - and what a waste of money - for 3 treatments! Dreadful service!
