I placed an online order for MS Office 2021 and received a code quickly, but MS says it had already been redeemed and won't let me redeem it. I emailed Nerdused support 5 times over a week, messaged them on Facebook, and opened two support tickets and received absolutely ZERO response from this outfit.
After 2 weeks of trying and opening a dispute with my credit card company, I eventually tried waiting till business hours in the UK and then tried *phoning* through Facebook and eventually got someone's attention, after which I was able to communicate my problem via Messenger. The representative got back to me after a short time and told me they were cancelling my order and I would get a refund, which they did, indeed, do. They *NEVER* offered me a replacement code as I wanted and as they promise to do on their web site. The problem is that in the meantime the price had gone up to triple what I paid originally (Black Friday sale).
