AVOID THIS COMPANY. Literally the worst experience...

AVOID THIS COMPANY. Literally the worst experience I could have imagined. Ordered refurbished iPhone X. Took nearly a month to arrive. Then days after getting it set up the battery was in shocking order, draining very quickly, the speaker was broken and the screen became unresponsive. I emailed and managed to get them to agree to fix the problems, sent off the phone and since then have had nothing but problems. They originally said it would take 5-7 working days to fix and send back, which then passed and when prompted was extended to 2 weeks. I was then told my case had been brought to management's attention and would be put to the top of the priority list, but still received incorrect information and didn't get my phone back for another 3 weeks after that, all the while me losing money on my sim contract and having no phone to use - v inconvenient. I then received the phone back and now 2 weeks later it is saying the battery needs servicing and that 'battery health is significantly degraded'. I dread to think what's going to happen next in terms of dealing with them. Wish i'd never bought from them.
