SOTC — poor services

My self kbl mittal. Booked a tour to bhutan from sotc in their group tour starting 13/5/19. The tour included 3 star hotel with bf & dinner. We had following issues:
1. The hotel at thimphu was not at all acceptable including the rooms & food quality.
2. The behaviour of the tour guide mr tharpola was unacceptable. He used disrespectful language & lost temper a number of times during the trip
3. Some of the itinerary itemes were not covered.
4. On the last day eggs were kept in the veg & jain packed breakfast.
5. Guide tried to take us in restaurants of their choice for lunch on some pretex or the other.
We wrote mails to sotc, brought the issues to the notice of their local agent mr megh raj but nothing happened.
Sotc even didn't respond. They were sweet till collecting the money for booking the tour afterwards they even didn't respond to our phone.
I opted for sotc since my earlier experience of australia tour was ok. But this one was horrible. At least i expected a quick response from them by responding to my mails & phone.
