Most of the institutions that I come across insist on their 'members' connected. Personally I hate mobile phones except when I am meeting somebody and need to know where to meet. Plus the use of WhatsApp (and such) video/audio connection that is essentially free. I am thinking of the ole days when I had to find a post office offering telephone connection to my loved ones in a different country than the one I was in. It didn't cost a fortune, but it wasn't exactly easy.

Straying off the point here .. I insist .. to these 'institutions' that it is impolite and not exactly formal to try and make proclamations and insistence to use .. mobile phones. Email address not connected to mobile phone helps ..

I am old school and the computer etc keyboard is far superior to the usual crappy miniature screen and keyboard format that mobile phone has ..

The final point being that trying to insist on having a letter comms with the 'institutions' may lead to delay in solving the problems created by .. 'institutions'. In other words they want you to solve their logistical problems of having to reduce their costs and increase their profits. Easy peasey analysis. Welcome
