Trai — Worst network nowadays

Address:

Kalimpong, west Bengal pin code 734301

Jio was once the best but now we can hardly use in my area pincode 734301
It is the worst now...i have been try to call customer care many times but luckily after 5-6 tries i got connected but the person i talked to as soon as he heard my netwrk was not good and i asked why is it so ? And till when it will last?? he pretended to not hear as long as i know he was hearing me this happened twice...i am highly disappointed with jio and the customer care as we all know we are doing online classes now i can hardly be able to attend the classes..jio please look after it or i might have to switch to other network
