Airtel fiber is one of the worst.

Have been using airtel fiber since 9 months now. I stat near station area and istg it has had issues every 2 weeks. Today as well the wifi suddenly stopped working. And the worst thing is even their airtel app (airtel thanks) is showing me error. I cant even call their customer care because apparerntly you need an airtel sim to call their customer care. Their app is so shit and glitchy. I mean how tf am i supposed to file a complaint. Would not recommend anyone to get airtel fiber.
