Dear sir, i pranav patel was using mobile no [protected] from last 10 years and using teachers plan 98/months from last 4 years
During paying bill suddenly i came to know that vodafone had changed my teacher plan 98/month to 198 without documents and without my request, as i had ask to rechange my plan from 198 to 98, vodafone had demanded to submit documents for such changes, hence i had ask how did you previously changed my plan from 98 to 198 but vodafone didn't able to answer hence i decided to switch from vodafone to jio
My query is still same and i request to trai to look in to tha matter and return my money from the date plan has been changed
