He visited today, says spikes after 10-15 seconds is a non-issue "Ittna toh aata hi hai". Says 1 out of 100 people care about this and only one other person in Nagpur has complained about this issue to him(one of you guys? has multiple connections he says). He says that he has done everything from his side but he will bring Nagpur NCO with him tomorrow. Offered me refund of installation charges after billing cycle if I want.
