Reliance Communications — wrongly charged of isd sms and advance rental plan

Address:

180013

I raised service request[protected] for my num [protected] for wrongly charging for sending isd sms and wrongly charging for advance rental plan in every month. But till now nothing has been done and reliance keeps on sending me bills for advance plan and isd sms charges every month which i never use. Earlier they use to credit the amount in next bill for wrongly charging of isd sms but now they are not taking my request and now they have also blocked the customer care phone call service so tht i ll not able to contact them and as well as they have diabled the customer service tab option on web portal.
Please help me in solving this coz this cost me around rs 400 extra in every month for the services which i m not using
