Bharat Sanchar Nigam [BSNL] — bad service and customer care is the worst

Address:

Vill-Chaksalem,Po+Ps-Patory, Dist-Samastipur,Bihar, Samastipur, Bihar, 848504

I am unable to call anybody through my bsnl mobile even if there is balance
I tried contacting the customer service 1503, only one tune was playing for the last 10 min for three times and no one answered.
My simcard no is [protected]
I recently got a recharge of30 ruppee of which 22or 23 was credited. Then i tried calling on many numbers but not a single call completed.
Also 30 ruppee recharge didn't show validity at that time but now i got a message saying that validity expires on 31.01.2020. So if you want to retain your balance recharge more.
