I am not sure to laugh or to be sad but it definitely turned me off from getting any deal from this company. This is what they have written on their Delivery and Orders page:

NOTE: Any cancellation, refund or exchange cases where the customer is rude to staff, abuses them or threatens, will be overseen by a company executive, cancelled and ignored. All rights of cancellation, refund and/or exchange will no longer apply ie. a refund will no longer be made and emails will be disregarded. No item will be able to be returned and the current order status will proceed as originally planned. GC’s PC’s strongly objects to customers who are rude and does not tolerate any of the stated above. GC’s PC’s will act against these issues with all its power to ensure the well-being of staff and our customers.

Most probably that segment may have been deleted when you read, but we got a screenshot of it just so we can share the horror or laugh at it.

Luckily, if you are in the US, there are still some cellphone stores such as CellphoneShop and Cellular Blowout that are reliable and still listen to customers. Use coupon code:freeship during checkout at cellphoneshop and get free shipping on your orders.
