Frustrated with Discovey Insure

I called your call centre to request my policy information only to be told that i need to write an email because my cellphone number has changed. I'm sure that there are other processes go authenticate a policy holder. I

wrote the email however have not received any reply. My question is, what if i had a death claim, i would be grieving and frustrated at the same time? I have been paying these policies from 2014, once i receive my information i will take my business elsewhere.
