Don't take any telkom deals **** advertising...!

Never take any telkom router deal...! Telkom is the worst ever. I took their route deal and its 10gb day and 10gb night.. I used the data 4 days and it runs out. During the day I'm at work and I use WiFi so I don't take my router with me in the evening I'm on Facebook only, I don't have twitter, Instagram, I don't download music or movies but it literally lasts only 5 days from the 1st-6th of the month... How is that even possible? I guys r absolutely pathetic robbing people of their hard earned money by promoting **** deals...
