3 won't help me return my router

[Makeitstop]

I signed up for the 4G home broadband on March 1st, the HUB & sim were delivered the next day & I immediately decided to cancel. It just wasn't right for me & not really fast enough for a 24 month contract. So I went on the live chat & rang & I kept getting cut off after 29 minutes, I now realise I was being cut off because of a fault between Xperia and Vodafone so not 3's fault. Anyway I finally got through & managed to cancel on Friday March 3rd. I chose to wait for a jiffy bag to return the router. 2 weeks later, 17/03/23, it still hadn't arrived so I called again. They said I would be emailed a DPD label in 16 working hours, by Tuesday because of the weekend, that never arrived. Thursday 23/03/23 I called again & they said they would send me another label the next business day. Well I still don't have it.

I don't know what to do now, I've already wasted over 5 hours on the phone & have gotten nowhere. I have one week before my 30 days are up & still have no way of returning it. I can't even send it myself since I have no address to send it to. Any help/advice would be appreciated. Anyone know what happens if you don't return within 30 days?

I would suggest to contact 3 and ask them to resend you a pre-paid label so you can return the item. If you are worried about if they have canceled your contract you can alway check to see if your SIM is still active. If it active, it's not been suspended.

Also not sure if you still access your 3 account via the app or on the site, but it should be listed if a label was sent under recent activities section.

When I cancelled my 24 month contract ...there was a light threat, that if I failed to return any equipment "as new" I would be changed. 

I choosen to send it back via Royal Mail (so they could collect it from my house). The 3 support advisor sent a label through no issues and the address on the label goes to Ingram Micro (P), Norwich ...I assume it's a 3rd party dealing with the returns?? anyway the label also states the cust ref and a department ref so it might be best not to send it back yourself.

There's an address on the cancellation form on this page. Quote any returns order number if you have one.

Some live chats allow you to print out the conversation; does 3's? If it does have another conversation and print out the conversation so you should be covered if 3 says you had to return the router in 30 days.

That doesn’t work because 3 never replied to me. 6 phone calls and 2 letters later still nothing. 
3 your service is rubbish.
