Poor Customer Servive-WD EXTERNAL HD

I am having problem with my External HD and raised an RMA number 81875959 on 21st Apr where in the Supprt executive  in India promised for pick up within 72 hours and today is 29th Apr and I am still waiting for the pick up.Everyday I am calling the Support people who promise that it will be picked up at any cost by the days evening and 6 days after the normal deadline have passed .I have lost faith in commitments from people.I hope this will do something to wake them up and keep with their promise.
