Totoodo.com — Unprofessional behaviour

Address:

Jayanagar, Bangalore

I gave my tablet for display change before two months to Jayanagar. I've been trying to get status of the tab and every time I try calling 2-3 times a week them I get one of the following :
1. version mismatch(!), and get back tomorrow, that never happens
2. Guy who collected my phone is on leave(for weeks), will arrange a call from head office, which never happens
3. No one at the shop, call so and so number, that number either disconnects my call or blocks.
4. Got a number of head office lady who also said I can collect my tab next day, next day onwards my call gets disconnected when I call.

No one is able to tell me why the job is not done in 2 months and when can I recieve my tab back. As no one is reachable either on shop or on phone.
