HI guys
for myself, I dont care I have been paying two ISPs for this month. it is not costing anyone a fortune anyway.
however I believe this 30 days cancellation is not fair and trap for people switching.
yes, I might be not smart enough to do my research.
yes, I should not bindly follow what the saless from NEW ISP told me to.
but I believe the world should not like this.
I just hope my post can help some avoid this trap or even some ISPs can change this stupid 30 days cancellation policy.
