Student — cancel activation of 349tkt plan

Dear sir/madam,
My mobile no. is [protected]. I received a call on 15th may at 3:30pm from airtel, saying there is a 349tkt plan, to activate send an sms to 222, which i did. I received a reply saying ' Your request has been registered. We ll revert back to u on d same via sms'. I have an existing plan of 999, i thought o[censored]sing the 349 plan for d coming month and switch back to my previous 999 plan later( which i was told by your company person, that it can be done by merely sending an sms). But when i talked to to another person on 121 he said we could change the plan back to 999, but i have to pay Rs999 again to get back!!!( even though the plan is valid for 2 years, it gets canceled once i have changed it to 349 plan) This thing was not told to me when the 1st person from airtel spoke to me( If such was the case I would not have sent the activation msg to 222).The first person had continuously made calls to me, asking me to activated this plan immediately, stating it was a good plan!!!, if its a case that the 999 plan wont be valid after activating this, is it not his duty to mention that( because why would any one change a plan, when previous is valid for 2 years, and get it cancelled, this way). I spoke to another customer care executive who told that i would be receiving a confirmation msg again after 24 hrs, in which replying a NO will automatically deactivate the request. I have not received the confirmation msg either!!!. So i was suggested to mail you directly. So since nothing seems to be working in my favor i would suggest u to kindly cancel my request for the 349tkt plan, and let continue with my 999 plan as before.
Please look into to this problem and the cancel activation of 349tkt plan.
Looking fwd to hear from you.
