Review I need a refund of my money.

I bought a techno x phone from tema branch February 2019 and in less than a month the screen went off, up till now I don't have a replacement and it seems nothing is been that. I have sent my wife twice to techno head office and still nothing, I was told they don't have the screen to replace, later they told me my wife was told to add up to take a higher phone(which was a lie), now they are tell me my warranty has expired which is also a bid lie so ask your people if I should find time from work and come there myself all your customers will who you people really are OK. You can't continue to decieve the public like that OK. I need my final by the end of Wednesday ok
