Bad service before I even set foot in the salon

I'd purchased a coupon, against my better judgement, for a couples massage session and made contact, as instructed on the coupon, to make an appointment. I was told by the person who answered to refer to WhatsApp to make the booking. In the automated response, there's an option to use an app to make the booking which I did and also found the coupon as an option which I'd selected and made a booking. This was promptly canceled and I got a phone call from a rather angry lady, whose name I won't mention, telling me I hadn't followed the process correctly as I should've called. Besides repeatedly telling her that this is what I'd done, she tried to make it seem as if I was the one who made the mistake of booking online when all I did was follow every instruction given to me. The cancelation was due to unavailability and she offered me a booking for late in December, which was a month after the initial booking. This wasn't a very pleasant experience at all, and I hadn't even visited the salon. Most likely, speaks volumes of the service.
