Hi,
I am a practising business lawyer and associate with a law firm providing legal solutions in various common law jurisdictions like US, UK, Canada, India, OZ, NZ, Singapore and Hong Kong.
I can draft the letter efficiently. However, my professional advice to you is that you should drop the idea of making a phone call to them as people often use call logs to allege coercion and intimidation.
So try to keep formal and in writing.
All your queries are welcome.
regards,
Divya Kumar
