The Professional Couriers — Non Delivery of Letter

I sent few business related catalogues to Lucknow through The Professional Couriers on 10th March 2010 and today is 17th March 2010 still now the Cover has not gone to the other party who is waiting for the same, due to which their business is getting delayed. Hope Our Postal Service would be more faster that this, felt we have customer services desk who would really help us but that too is vain. They have no answer for any question we asked and they don't carry about complaints. Think they are most used to these kind. Customer is King, our Service is to satisfy the customers right requirement all these things are just good for nothing.
