Dell — Celebrate Dell se offer... Offer has not yet received

Dear Team, I have bought Venue 7 3740 LTE in the month of November where Celebrate Dell offer was on where power bank and and bluetooth headphone was free. As per offer I have to send a DD of 699 which I have send and the confirmation of receiving of DD was send by mail to me on 12th Dec 2014, where I got the confirmation of receiving of DD and also got confirmation of dispatch of courier within 15 working days from respective mail ID. After 15 days when I didnt received anything courier, I again send a mail on 4th Jan 2015 regarding non receiving of couirer as per committment made by respective authority, Then on 5th of Jan they again send me a mail regarding completion of Validation process and delivery of product by next week. Again when i didnt received the courier by the committed period i again send a mail on 19th Jan 2015 where in they have confirmed that my couirer has been dispatch on 14th by track on courier and has also given respective id for confirming the same. Which i have confirmed and came to knew that the courier is laying with track on courier. The courier which was send to me on 14th Jan 2015 was been send back by the local courier office back to Bangalore on 21st Jan 2015 as per the track status which can be viewed through the site of Trackon courier. I have spoke to the Branch Manager of Track on courier in Nagpur he said that Godhani doesn't comes under there service area. Firstly I want to bring to your notice that the local office is present in Sadar in Nagpur and my place ( Godhani) is less then 6 kms from there office. Secondly I want to ask a question if this area doesn't comes under there service area then why this courier agency has not called me up in my mobile to intimate me about it ? When asked this question to local BM of courier company, he said that they send SMS which I never got ... What a joke...we are in technology world and we knw that the next generation is of technology but still the courier company are lagging behind in it... hear I want to ask one more question to courier company that why they have not called me up on my mobile when they were having it?... Don't you smell it as a pure unprofessional approach from a local courier office, customer harassment, doing job just for the sake of doing, all irresponsible people are being appointed in the courier office which you have hired, do u really feel that the courier company which u have appoint is professional enough to be hired...this and many question you should ask yourself when your appoint any agency... you all are professional company but this experience has made me feel that professionalism itself is missing in your company... your commitment fails which you are giving to your customer, ur agencies commitment fails which u have hired ... I need an explanation on it... pls don't send me automatic generated msg... I want a proper explanation on my delay... I also want confirmation when i would be getting my product...a committment which would be fulfilled... This experience is the worst experience in my life...
