It’s only a QC problem if it’s beyond Omega’s tolerance specifications, I’m guessing it is within those, probably close enough to be borderline.
Now if you had purchased it from the boutique in question, then maybe they’d go into bat for you, but as you bought it elsewhere, they aren’t inclined to go to the trouble on your behalf, especially as there is bugger all in it for them.
If you were to take it to a different boutique, with the same issue, maybe they’d be more helpful….. maybe less helpful….. it all comes down the the people involved and circumstances including you.
Now I don’t know you and I’m not saying anything about your personality.
But some people don’t come across very well when making a complaint, this may not be intentional, and it may have more to do with the attitude of the customer service counter jockey than the customer.
My point is that when it comes to the customer service experience there are too many variables, that no corporate customer service policy can take into account.
