Onsitego — Repairs for a room cooler under extended warranty

Address:

In Ahmedabad

From last 3 days we have been receiving messages that the service technician has been trying to call us but we haven't received a since call or message. Today received message that the service technician will come between 2-6pm. He lands up at my place at 8:30pm is this the timing to come to someone's place during dinner time and when we are almost trying to retire for the day. The person is still at our place repairing it's past 9 now. Is this what service is? What was he doing the whole day.
