I am also facing same issue. I have 8mbit connection over copper with IPTV. When I got connection, only copper was available here, however, now I think they have optic in my area as they had sent pamphlets few days back.
I have been, more or less, satisfied with PTCL. Especially with unlimited account which my family heavily use for streaming.
I am in Phase 8, Bahria Town, Rawalpindi. Where are you located? Just asking to check whether this issue of PTCL is nation wide or isolated to one particular area.
