Amazon — Return the phone

I ordered Xiaomi 11 Literally NE 5G on 25th October. The order number is[protected]. My friend gifted me the phone, so I tried to cancel the order. But failed to cancel it though I tried several times. Every time it shows that some thing wrong happened please try some time later. After receiving the phone I tried to return the phone using app but the same thing happened several times. Ultimately on 6th October I chatted with someone and he said that the the phone will be pick up by them. But they didn't do that. On 10th October I chatted with someone and he arranged a telephone conversation with a gentleman who also promised that they will pick up the phone with in 48 hours. But didn't fulfill his promise. I got the from +44 [protected] at around 5.30 PM. Please take necessary action so that I can return it as it has no use value right now. I look forward to hearing from you.
Sincerely
Nitish Datta
