Clear-Coat

I regret for using the service of Clear Coat for the last 3 – 5 years. All my phones and family phones, one of the procedure is to get a cover and get a screen coat right after we purchase the phone. The service itself is very expensive compare to what we can do ourselves. At $ 25-​$ 50 installation and $ 7-​$ 13 for the re-​installation after that. I know we can get a cheap screen protector online to the more top of the line costing 50cents to $ 10, but the reason I use them is because of their LIFETIME GUARANTY, if something happen, they will reinstall at installation cost, which usually around $ 7, it might increase depend if the Rep wants more pay or not, but even at $ 7, the rep can get at least $ 5 for 10mins of work.
I was okay with all that, as long as they GUARANTEE their service. Unfortunately, this time, the screen broke on the iphone 6 and the person who changed the screen threw away the broken pieces with the front screen protector, which is normal (and I’m not even going into the quality of the screen protector here). But I still have the back protector. Reason I’m saying this is because their policy require the old pieces back as receipt. That’s why a couple of day back during blackfriday, I told the rep what happened and asked if its okay to only have the back screen as proof, he hesitated but he said it should be okay. Just bring it in and he will do it. But today, I brought it in, it’s my gf’s phone by the way, to a different rep, and it’s the second times she installed for me, but she said she won’t be able to do it. She told me to contact the rep that said so (I don’t know who I talked to) Just like I check before, I just need the front done, use the old back piece as proof, but install the front only. They don’t have to redo the whole thing. But they won’t do it.
I’m not being cheap, if I am, I won’t go for such service. Again, the warranty is what interest me, BUT THEY DON’T HONOR THEIR WARRANTY. I unfortunately have spent a couple of hundred dollars here, stupid me. I’m not sure if its their customer service, or they don’t care about keeping a customer, but whatever it is, they sure lost my business.
