well i have been using BOTH.
and this is how i would rate them.
LDN
service/speed 7/10
customer service 10/10
PTCL
service/speed 8/10
customer service 0 /10
in short.....LDN has very good speed , but a lil lesser than PTCL , but their customer service is stunning.
as for PTCL.......it runs better than LDN....till it runs.......onec u face ne problem.
u r literally DOOMED.....my connection stopped working onec , and one week past , no one came to even inquire wats wrong.
and with LDN , if u launch a complain , ppl call you and inquire abt the status of your problem , and confirm when it gets solved.
i have had troubles with LDN aswell. but at the most , it takes them 2 days to fix your connection.
PTCL is only about better speed.
onec you fall into a problem , u r doomed , it would never get fixed.
on a 2mbps PTCL i m recieving a download rate of around 150kb during day , and 200+ at night
on a 2mbps LDN ,m recieving around 120k during day....and 180+ during night.
i have LDN at my home. and PTCL where i work.
so i recommend LDN above PTCL.
as customer service plays a very vital role , in the TECHY things.
