Cinna-none: Wrong order given to courier, then refusal to honour correct order.

I have just had a ridiculously unpleasant experience with the Cavendish branch of Cinnabon. I ordered a Cinnabon through UberEats, whom I have also unfavourably reviewed in this regard. The crux of this poor experience was that the courier brought me the wrong order. He maintained that it was because Cinnabon had given him the wrong order, hence why I assign blame to Cinnabon as well as Uber Eats. In spite of the fact that Cinnabon gave the wrong order to the courier, they refused to give the courier the right order when he had to trek all the way back there. So Cinnabon keeps my money, and I am left in the lurch. It is impossible to contact the Cinnabon. I suggest you at least install some kind of phone in your shops that isn't the general line to the Cavendish Square security. This is useless for business purposes. I also suggest a simple system is perhaps put in place to ensure Cinnabon staff do not give Uber Eats couriers the wrong order, so that this sort of thing doesn't happen. It is as simple as writing the customer's name on the bag the order comes in in permanent marker. I am very unimpressed with both Cinnabon and UberEats, and, had it not been due to the mess-up by Cinnabon employees, I would not have had any of this headache.
