I purchased one SAMSUNG E7 Mobile from EASTERN LOGICA INFOWAY LTD, 14 C R AVENUE, KOLKATA-72 ON 13/08/2015, WITH A OFFER PRINTED ON THE PACKING BY VODAFONE COMPANY THAT 2GB OF 3G DATA WILL BE OFFERED TO THE BUYERS OF E5 & E7 SAMSUNG MOBILES PROVIDED VODAFONE SIM IS INSERTED FIRST TILL THE OFFER IS GIVEN BY THE COMPANY. I PURCHASED VODAFONE SIM WITH PHONE NO 9836279048 FROM THE SHOP ON 14/8/15 AND THE SAME WAS ACTIVATED ON 18/8/15 AND THEIR HELP LINE INFORMED THAT THE DATA PACK SHALL BE GIVEN WITHIN 48 HRS. ON NOT RECEIVING THE DATA PACK I ENQUIRED FROM 199 WHO SIMPLY DENIES THAT THE OFFER HAS BEEN CLOSED AND THEN HE CUTS THE LINE. IT WAS ON 20/8/15 AT 19:56 HRS. I INQUIRED FROM THE SALES BOY OF EASTERN LOGICA INFOWAY LTD SHOP WHO ALSO TOLD ME ABOUT THE OFFER WHILE PURCHASING THE MOBILE (MR AZHAR MOBILE NO 8100636833) WHO THEN TELL ME THAT COMPANY DOES LIKE THIS WITH MANY PURCHASER AND GIVES TO FEW PERSONS. HE ALSO INFORMED ME THAT HE SHALL ALSO COMPLAIN TO HIS HIGHER MANAGEMENT.
