Bt[FONT=Source Sans Pro, Helvetica Neue, Helvetica, Arial, sans-serif]w m[/FONT]ost of you don't know this but the 4mbps connection is capped at 300gb after which they charge you extra. They call it unlimited but its not. Call them and you will find out. Unlimited only truly starts for the 8mbps@7000 package
They also told me on the phone if they upgrade my connection to 8mbps it is going to still remain capped at 300gb (even though it is advertised as unlimited). It will remain so till the 31st of January.
I have a 4mbps connection. If i were to ask them by my own self to upgrade my connection to 8mbps they would do it for free. But after some time if I dont like it and then i ask them to downgrade they said they will charge me 1500 for the downgrade
Though if PTCL were to upgrade you to 8mbps and then u ask them to downgrade back to 4mbps I am assuming they dont charge you for the downgrade them provided you request it before february. I am not sure on this though
