I have been getting two free add-on cards inspite of cutting and surrendering the card along with a request for cancellation. When my original card get renewed, they once again send the pair of add-on cards. They are not bothered about telephonic complaints. Now I stopped making complaint. Once they charged a renewal fee of Rs.750 on the add-on cards and reversed it after big shouting. I never used the add-on cards and just ensure that the add-on card balance is 0.00 by checking it in on-line regularly.
