Very bad service from Huawei

I bought a phone online from Huawei on the 1st of October 2024. It was delivered on the 3rd of October 2024. While I was busy with settings it automatically switched off. I logged a chat on their website and I was advised to send it for repairs. At repair centre they told me they can't fix the phone because it's less than 7 days. I then called the customer care centre and I was told to log a return from, did that and I was called to be advised that if I want a replacement phone I need to log a replacement form and they will send a courier to bring a replacement phone and I must give him the faulty one. Today, the 10th of October the courier calls me for collection, when I ask him if he has a replacement phone he said he didn't have. I called the customer centre and I was told that I have to give him the phone, they will check it first and they will replace it. I waited for 10 days for a phone and now I'm told to wait for 10 working days to get my refund. What a nerve
