Jio sucks

I recently shifted to baner nd thus got a new jio air Fiber connection ! Nd ohh goddddd !!!! Itsssss sooo horrible ! Getting 0.5 mbps of speed when I had paid for 100 mbps ! Tried calling these bastards customer care but just no action being taken ! Technician came once but he himself couldn’t identify the problem ! When I asked him to connect me to his higher authorities , he said woh khud kuch kaam nahi karte ! wtf !!! Bc agar nahi aa rahi jio ko range mere areas mei toh maa chudane woh connection bithaya ?? These motherfukers aren’t even giving me refund of 4250 which I had paid for 3 months minimum plan !!!! Today’s almost a week ! They say there’s no refund policy !!!!!
