SOTC — badly organized, most unsuitable for senior citizens

Group of 6 senior citizens booked a tour of the far east from 27 march to 6 april. From day one there was problems. No meals were booked on outbound flight to malaysia. We reached kl hungry and tired and almost immediately we had go for sightseeing. Half day tour of malaysia took place at night where we hardly saw anything. Shows how badly everything was organized. Next day prog was equally unsuitable where there were mainly rides and water sports. Most nightmarish of the whole trip was the journey to singapore by road. The coach started 2 hrs late and we had to stand on the road with all our baggage. We drove for 4-5 hrs nonstop and when we finally stopped it was only for 15-20 mins. We were cheated by sotc as they said they will be arranging a pvt vehicle for us but changed at the last min. At both malaysian border and singapore immigration we had to carry our baggage ourselves and wait in long queues, most strenuous for senior citizens. We were not informed abt this by the travel agent. When we reached the pick up point nobody was there to receive us. After constant calls to the local agents there was no response. When we finally got through we were rudely told they have no information. We had to take a cab to hotel. Throughout our stay in singapore we got no info abt where and when we are going. We had to make constant calls to local agents which made our telephone bill high thanks to the indifferent and callous behavior of the agent.in pattaya again sotc goofed up everything. They arranged a trip which the local agent said was dangerous and unsuitable for senior citizens. We had go for another prog for which we paid 3000 thai bhats out of our pocket. Just shows the throughly careless don’t care attitude of sotc. When we reached bangkok we were rushed off for sightseeing even before we had checked in to hotel. The next day nothing was arranged for us and we contacted sotc they said that we didn’t inform them that we wanted a prog to be arranged on that day. Whose duty is it to arrange prog... The customer or the travel agent. We had to fend for ourselves by arranging a prog ourselves and paying 7200 thai bhats out of our pockets.
Surely for all this torture and trouble we have been through we deserve at least compensation for what we have spent.
