Dyson TP7A Purifier Cool Fan

This fan did well for the first 7 days, after that it started to squeak, then it had a very high pitch when blowing air, and the. It just didn’t stop. I tried to clean anything off of the fan but I didn’t see anything that might have caused it. Then I read on other reviews that this fan happens to do that to other buyers. No I’m waiting on my refund and I sent this fan back on 8/7/2023 and it’s 8/17/2023. Not sure why the refund is taking so long for this item, and I did buy other things that I happened to send back the same day and I was refunded either the following day or max 3 days later. This is ridiculous from Amazon to take this long, knowing that they have received the item, it’s been sent via UPS, and I have a tracking number showing it’s been sent. Definitely be warned with this item. Something is very fishy… this was an Amazon Prime day sale item. What a waste of time and money that I’m still waiting for.
