Thane, Maharashtra, 400606

Dear sir / ma'am

I am using vodafone from many years and i am facing many prombelms from last 2 months but i was ignoring that, before 6 months the person from vodafone ask me to move for postpaid plans but the person has not given information about the roaming charges, that time hv took 2 postpaid plans, 6 months plans were working fine but now this month's bill amount has suddenly got raised so hv called costmoer care he told me about this month they hv charged roaming charges, now it's on height i am traveling to maharashtra my native place from mumbai, other all networks are providing free roaming for all over india n why vodafone applying roaming charges in maharashtra? This time i won't be able to make a payment to you because of this useless charges for both the numbers.
Pls do something asap
I want to switch my network from vodafone to some other networks

Thanks
