unprofessional business practice

I made numerous booking through Safarinow.com for a trip through Namibia in August. Due to the coronavirus and border closure I have had to cancel my plans. I have attempted since 6 July 2020 via phone ( no answer) and numerous emails to 3 different email addresses without success. I have been making bookings through Safarinow.com for many years and find this non response most unacceptable If this is how they treat their customers you should be weary about doing business through them.
