Amazon issue

Lost phone

I sent a mobile phone for repair back to Amazon on the 24+3rd June. They received as the status changed and I had not heard back anything after 14 days so thought I get in contact.

Over the last 4 weeks, I have spoke to Amazon on the live chat 10 times.... The first 8 times they told me someone from repairs team would get in contact within 48 hours and no one ever did. The previous two times, they said they would give me a refund and I would get confirmation email with refund request from the repair team within a few hours but never did. I have also emailed the repair team separately on 4 occasions asking where my phone is. I'm convinced it has been lost.

The repair status has now gone from my order and it just asks "have you received your item yet" and when I click no, it says to contact Amazon Cs which I do.

But I'm running out of ideas. What can I do? The device so far has been terrible
