False advertising on Memorable special

I recently made 2 bookings for Sun City using the memorable promotion code. Neither of my bookings came close to what was advertised and when searching various other dates I only came across the advertised price once!!! Come on guys, who are you trying to kid....that's false advertising. Also my experience after booking (not at the advertised rate) has been far from a pleasure and up to the standard I've experienced in the past. I booked online and entered my credit card details to pay. That evening I received a message from my bank notifying me that the expiry date was entered incorrectly. The same thing happen with my second booking and I made double sure that my card details were correct. I phoned the call centre yesterday and was pushed from pillar to post to get my card details sorted and it wasn't even my mistake in the first place. Eventually I got through to a helpful lady in the finance department who assisted me. Hopefully our stay will be better than the booking experience. You really shouldn't advertise promotions or specials when you don't actually offer these to patrons.
