Inroducing of new technology and services is highly appreciable and shall earn more revenue for PTCL and also controll over fuel/power consumption and its misuse as well.
My connection is through Misri Shah exchange and up until October 20, this upgrade is not complete. My DSLconstanatly disconnects. Does anyone know when this upgrade will be finish. This is annoying and I am thinking about getting Worldcall and canceling PTCL.
