Q-Mount review: Online order not fulfilled, no response to follow up queries.

Placed and order on 17 July 2023, the confirmation of the order was prompt and professional. The tracking number provided did not work on the DHL website. Sent an email to Q-mount on 27 July, they responded promptly on the 28th of July informing they would investigate, and send the package via express if the parcel was found to be missing. Heard nothing thereafter so sent a follow up email on 5 August, no reply. Checked with DHL who informed the tracking number is invalid and that I should follow up with Q-mount. Still not receiving a reply from Q-mount I sent another follow up email on 11 August asking the status of the investigation. Q-mount have not responded since 28 July 2023. I was confident this was not a scam website, given there are independent reviews, however now I am not so sure.
