Ortel — no response and harassment

Address:

Angul, Odisha

I am a internet user of ortel communications and i have been facing a problem with my modem which restarts of its own in about every 5 to 10 minutes and the connection is faulty. i have informed this issue to them several times and they didn't at all respond me and they even closed the complain without bringing it to my notice. my membership number is 920206 and there are several complains which have been closed unresolved.
Their customer care says that there will be someone to to deal with the issue next day but no one comes and they don't even call back. they disconnect the call in between the conversation and harass the consumer.
my complain no. 2533937 is not yet resolved and almost 16 days have passed since i have launched it.
