Amount deduction By MTNL dolphin

Location/place: faridabad

Name of company/service: mtnl, dolphin

I am also facing same problem in dolphin connection. From 12th july the money is being detected in interval of 7 days. I have not activated any disc pack service.The message is coming from 53737010. They are doing it themselves. Earlier in last year they activated some song year and deducted 30nRs. Neither they deactivate service nor they refund the money. My number is 9868492417. Please do the needful
