Wrong Email and Cannot Get Support

I accidentally misspelled my email address when placing an order and now I cannot access the order to change this issue. Since I cannot see the order in my account, I cannot contact customer support online. I've tried calling several phone numbers and keep getting redirected to a recorded message that says to contact customer support online. At this point, I just want to cancel my order and buy a laptop somewhere I can get any support ... but I can't even seem to find a way to cancel the order
