BAD SERVICE

I have a Oukitel WP5 Pro phone and the phone stopped charging all of a sudden. So, I sent it in to Tsukuru t/a Oukitel South Africa for repair. Sent it in to them to assess and quote. They phoned me a few days after they received my phone and asked if I wanted to replace my screen as well as there was a chip in the screen. I said no, as it did not interfere with the functions on the phone plus I didn't have the extra cash. They continued with the repair of the Type-C port which was the problem with the phone not charging. They repaired it and I received it back a few days later. Upon receiving my phone back, I noticed the the chip on the left top corner of the screen was gone and upon operating the phone I saw fade spots around the edges of the screen, I also noted a yellow inner halo around the screen and a crack in the top right corner of the screen which limits the swipe functions for the top of the screen. I then sent an email to Tsukuru t/a Oukitel South Africa to tell them about the problems I have picked up. But they say that my phone arrived that way. They sent through a photo of my phone when they received it. And from that photo you can see clearly the chipped top left corner of the screen. So, I sent a further email with photos showing that the screen was replaced and it was faulty and asking for a new screen or replacement phone, else I would need to take it further. To date I have not heard back from them.
