I too had the same problem as you with Telegram.
I’m finally on it. Romana is on there with more than 66,000 followers.
I don’t know how to help you..
I too waited for a message that never arrived.
I ended up installing it on my PC at home (Windows) but had to use my cell for the code because
my landline phone never gave me squat.
I didn’t want to have Telegram on my cell because of the cost for data..
Romana replies on there daily plus has more than 80 pages for Help for those who need it ie. Groceries, Rent etc.
