Tata Docomo — Deliberately wrong info from company

Address:

Mumbai City, Maharashtra

Dear sir..
I m using Tata DoCoMo since last 8 years.
I got numerous msg frm DoCoMo regarding spl rechrge of 87.
When I talked to cust care today..
that personnel said " this recharge is not available now".
and she suggested me a spl recharge of 249/-
whn I availed that 249/- rechrge..
again I got the msg abt the spl rechrge of 87/-.
this instance is now very regular with my number.
kindly do something needful.
regards ..
