I just discovered that my 2MB Broadband connection has been upgraded to 4MB from 1st Nov 2013 till 31 Dec 2013 the price remains the same Rs.1549. By the way PTCL did not inform me regarding this. I just discovered it by myself. It's on their website as well.
The catch is, if people don't call them to opt out of this package before 31 Dec, they will be charged for a 4MB connection Rs.1999! Shady marketing practices by PTCL. By the way this is not the first time they have tried this trick.
