Sun International companies poorly and unprofessional department of RESERVATIONS

I am submitting this on behalf of my elderly mother who is not an expert on the modern technology of using the internet and other tools to help them. She's solely reliable on their resevations department and telephone service. Poor service at resevations, poor and unprofessional service at your reservation department. Elderly people who have bad technology experience, and aren't experienced enough to make on-line resevations, and rely solely upon the resevations team to provide them with the best as possible service and assistance with their resevations. Kindly contact *** urgently and provide us with written confirmation of receipt of this complaint. I am astonished that a multi international company such as Sun International has to be reminded by the customer of this poorly and unprofessional services.
