I rarely found my internet working when I had my Broadband provided by mtnl.
Horrible service, reliability and not at all trust worthy. This company gives no damn about their customers but never forgets to send the bill on time. It is overpriced and useless.
MTNL never fails to give a reason to get hated, whenever I have filed a complaint, either nobody shows up to resolve the issue, or the executives that they send are over aged and have no knowledge whatsoever about their job.
My issue was never resolved and I ended up changing my internet service provider.
Please stay away from this company.
