T24 Mobile — false promise to t24 customers

On 15/102017 i made purchase of rs.2021 from big bazar (Future retail limited) r mall, mulund west, mumbai 400080, vide tax invoice no.[protected].in the invoice, there is a remark "you are eligible for rs.15 free talk time, contact t24 mobile kisok for details. I approached the t24 counter near the billing counter but your representative refused to load the free talk time of rs.15? Your man asked me from where i bought the sim, if it is not from big bazar, i am not eligible. If i am not eligible for free talktime rs.15 in my t24, why such a remark?.in my last month's purchase from the same place at big bazar, your people had loaded free talk time in my mobile. It is a shameful matter from a big company like yours. I wanted to purchase a mobile also but your man's behavior made me to leave from the place without buying it.
