[Resolved]  Tata Indicom — Deactivation of regular plan, On activating 7 days roaming plan

Hi, I am old customer of Tata Indicom, my number is +91-[protected]. Recently on my business trip I have activated roaming plan for 7 days but when I came back to my home town my regular plan of 349 is deactivated. I made call to customer care and shocked for their response, that is "If you activate any offer then your previous plan will be deactivated ". But, this is only for TATA INDICOM customers only not for their TATA DOCOMO. When I asked why and what is the reason for deactivation of previous plan, they are not responding properly to questions. I just want to file one complaint on this issue, because they are not providing minimum information on recharges. In their official web site you don't find information on " previous plan deactivation if you recharge with new plan(even if it is roaming ). Will you please provide me guidelines to file compliant, I don't want to take this issue easy. thank you
