On 1st july 2016 i got an sms n its written unlimited for 1 month *444*196# i just checked n went thru n suddenly ive seen my balance(Rs 196) deducted n my all previous 3g balance(Rs 376 for 2.5gb) gone .
My ques is how vodafone activate this plan without my consent ??? N if they activate then where was my previous 3g( 2.5 gb) balance ???From their sms(*444*196#) didnt mentioned anything i.E if i put this n dial, it will be automatically activated or my all present 3g balance will be deactivated.
So how vodafone done this thing without my consent ...It was absolute cheating ..I tried cust care over phone but didnt get any solution .I also have sent email, but i got replied that previous 3g balance can not be restored n present plan will be deactivated n will offer rs 163 talktime ...
But how to accept this cheating ? I spend 376+196 all of my amont gone n will offer 163 only (For vodafone ref correspondence is [protected])
