Hello, I have o2 unlimited sim card. I have been using it for 5 months now. Since last 2 weeks the internet has been not working or working really slow like 10Kbps. I am supposed to receive 50 Mbps and in my location it is generally around 30 Mbps, but last 2 weeks have been really problematic. I called customer care as well and each time I receive a response that it will be resolved in 2-3 days. And still no resolution. I and my wife WFH, and it is really affecting our work as it is all dependent on the good internet connection.
