How much it is to fix an iPhone 5c smash and unresponsive screen?

About a month ago I smashed my phone, I had it fixed in a local phone repairs shop called mobile street it was £60 they fixed it in 45 mins, it was only smashed the screen was still working. However it looks as though they have just stuck a screen on the top. I want to get my phone fixed again. I have dropped it a few times. And the screen has now got colour lines and about a third of it has go black. It is smashed. It is unreposive yo the touch. How much is it to be fixed?

Considering the digitiser (glass) and LCD (display) are fused together when sold and only cost about £25, it would be stupid to buy them separately, remove the old LCD and attach it to a new digitiser, they probably did not just stick a screen on top. Looks to me like you've fully broken your digitiser and the LCD has had a good smashing too. If you go to the same place you'd be looking at about £60 again, but I'd charge closer to £50

Why not take it to an apple store? Get a professional to do it, not these off the wall repair people.
