Jomashop Jomashop don't understand Customer Service Brooklyn New York

I am very disappointed with the lack of service from Jomashop after buying a Heritor HR2401 watch and receiving two watches and being charged twice. The error was caused because I was unsure the first order was completed online (an issue with Jomashops website or my web connection?) but was told by email by a Jomashop employee that no order had been received and I should place the order online again! I did this and received two watches and was charged twice. It was clearly their mistake by telling me my order had not been received but they refuse to take responsibility I expected fixing this problem would be easy and quick- however, all I get is unhelpful, rude junior employees.
It is clear Jomashop does not have a customer service culture- their senior managers are not involved in ensuring good service.
Beware of this business - I certainly would not trust them with an expensive watch purchase
