Trackon Couriers — Courier not delivered and no customer care number works

I placed courier service request on 2nd September from Pune to Bangalore with docket number[protected]. By 4th September it reached Bangalore. On 5th September, Saturday it was marked as out for delivery but it was not delivered. On Monday, I registered a complaint for which I received response that delivery time has not expired. On Tuesday, I contacted Bangalore office. They informed that delivery guy has taken courier with him and since 2 days his phone is switched off. None of the office staff picks up call. When finally on Wednesday they answered call, they told that it will be delivered. The staff is so rude at Bangalore office that they talk rudely and cut your call even when they are at fault. When I tried to call again in evening their phone is off. None of the customer care numbers of trackon work as no call is ever answered. No use of registering complaint as they never resolve even after 3 days of their given time. Staff is rude. No way of complaining. Pathetic services. Till now my courier has not been delivered. How can they let delivery person take the courier if he has no intention of delivering it on same day? It takes 2 days for courier to reach from Pune to Bangalore but even after 4 days it is not delivered within Bangalore. Please improve your services and stop fooling your customers.
