Coinme review: Customer service and app platform

I used to use this service quite often a few years ago and I did not have the same experience that I did the other day when attempting to purchase Bitcoin at one of the Coinstar kiosk locations. After receiving my voucher. I went online and downloaded the app, which continued to crash over and over and over and was not usable on my phone. I attempted to go online to the website and create an account using the phone number that I entered when purchasing the voucher and it continually told me that there was an error that occurred and that was all it said. I repeatedly attempted to contact customer service through their live chat that they say is available, but no one was responding to any of my messages at all. It also indicates that there is an e-mail in which to contact customer service, yet there is no e-mail that's specified anywhere that I can find. And the phone number that's on the voucher only allows you to leave a phone message regarding a fraud incident. But nothing else. So I'm without any options as to what to do with this voucher that I've purchased because I can't redeem it and I can't get into an account and I can't contact customer service.
