I've never had any company offer worst customer service.
- called in and submitted an issue with their payment module after I spent 1.5 hours trying to submit a PC express delivery order, and I spent 20 minutes getting someone on the phone
- received a ticket number
- two days later received an email stating I hadn't replied and that they were going to close the ticket
- I called in again, spending another 20 minutes doing so, and told them I would like to have someone deal with the issue straight away
- they would not transfer me to someone who could actually deal with the issue
- the next day, I received an email saying the ticket was closed due to a lack of response by me
RIDICULOUS
Recommendation: just go to the store and don't try any online option
