Idea Cellular — complaint against idea for dropping me in another plan

Dear sir,
As iam customer of idea company, prior to idea i was the customer of airtel but from idea company a excutive and his manager calls me before two months and expain about the scheme of plan 211 (Excluding tax) and i accept that plan and convert to idea.
Now i got the bill of rs349, regarding this i asked to customer care, then he told me that they drop me in plan 389. This same thing had done by airtel also, so when i received this idea chip i clearly told the marketing excutive to drop in plan 211.
With whose permission idea have done this mistake and i want to know who gave the power to these excutives who are speaking false statements.
Today when i asked idea customer care person (Srinu), he told me to drop a complaint mail. Iam asking to your organisation thats what you are doing your work or simply doing fraud with customers, please look in to this and solve my issue.
My first conversation with shiva prasad, he show me stars in day and iam attaching audio clip of conversation for your persual.
And my second coversation had with his manager, i clearly spoke to him that i can't afford the bill morethan rs 250.
Please take immediate action on shivaprasad ([protected]&[protected]) and his manager ([protected]) and whole organisation before others will suffer.
Iam attaching all excutives audio clips but i really believe all are doing fraud.
Sir please take immediate action on this before people suffers.
