Lost my paid app on upgrade

I upgraded my phone to iPhone 7 and I have lost my fully paid app as well and I am not getting a response from them is either.restoring from purchases just gives me the basics and takes away all the others that I have paid for and is asking me to pay again.....
spoke too soon ..., support for back to me quickly and gave me a link to reset the app back to the full paid version ... thank you support!
