No surprise there, they are always clueless.No clue bro, I spoke to PTCL help line, the local line man and exchange people, every1 is clueless..
What I did notice is that this issue popups on my end whenever there is a " Bijli ka jhatka " from wapda, like last night after a jhatka my UPS kicked in and right away I saw line stats to drop and shitty net as an end result. So maybe there is a connection with the unannounced loadshedding, PTCL backup batteries and the obsolete PTCL infrastructure which breaks down every other day!!!
