This will be really long but I’ve had the same issues with Amazon and now get my packages delivered to a locker.
The main issue is with the drivers, as even when
I’ve been at home they sometimes barely knock the door and leave within seconds, then say they couldn’t deliver the package even when no one is home.
Then other drivers will leave packages sitting outside my front door, which is also on a main road and people constantly walk by.
My delivery instructions are completely ignored by around 90% of drivers. I have instructions to deliver to a neighbour who is extended family, rarely happens.
I’ve even tried leaving a wheelie bin at the side of the door and saying leave the package in there, again ignored.
They also have a habit of mixing us up with the same number on another street as we’ve received packages for them before. I’ve called Amazon about this and they say ‘just keep the package or discard of it’. That’s likely happening to some of our orders too!
People saying to arrange deliveries for when you’re going to be at home only goes so far when Amazon have a habit of changing delivery days or orders getting delayed until hours later.
This is going to sound completely overdramatic but at one point I emailed Jeff Bezos’ email address. I never received an order at Christmas which was all presents for my kids and DH, totalling nearly £250. I don’t know what happened to the order, I just know I didn’t receive it. I contacted multiple times, was told at first to allow 48 hours in case it was just delayed and marked delivered by mistake. Phoned them, emailed them etc only to receive a similar email to you OP. I wasn’t even asking for a refund, I asked them to send a replacement order because I wanted the stuff! So I ended up contacting Jeff Bezos’ email (my DH still laughs about it) and actually got a reply a day later (from his assistant it said) who gave me a full refund and a gift card for the inconvenience! I then bought the presents from elsewhere because I didn’t trust getting them on time from Amazon after that.
Between this issue and charging extra for ads on Prime, I don’t think I’ll be renewing my membership this year.
