Poor customer service at Daniel Wellington Gateway

I recently phoned in at Daniel Wellington Gateway and reserved a watch. When I go to the store to make payment and collect, the watch was no longer available as it had been sold even after the staff at DW reserved the watch and assured me it is available.

As this was for a gift on the day, I took another watch however, I'm unhappy with it and would like to know if i can exchange or the return policy but I am unable to get a hold of the store at Gateway. I've called in numerous times on different days, even went onto their live chat and still did not receive any assistance. At first the number was incorrect, now the phone continously rings all the time with no answer at all.

I'm disgusted at the customer service from a store as big and renowned as Daniel Wellington and do not even wish to purchase again due the extreme difficulty in trying to contact the Store. There's simply NO customer support!
