ISP problem with STC

around last monday the ping rose up to 300+ and wouldn't go down, soon i realized it wasn't just friends also had this problem (they too use the same ISP) its "STC" so im hopping anyone could contact them and resolve the issue? and i have already submitted a ticket to riot support,note that im in riyadh and my friends live in Jeddah so Im pretty sure its STC :/
