Airtel(against) — I ported my number from Airtel to jio without any dues and now it say pay your outdues

As basic the operator allowed the port request after my dues were clear and it took 4 days. Everything was fine my number was ported and now they want me to pay my bill cycle in both the telecom company for the porting month.
I went to jio office and showed the dues were clear as I was postpaid customer and I went to Airtel office and they told me my dues were clear. Porting went smooth as there were no dues and now after my becoming jio customer Airtel is harassing me for paying without any reason and they blocked my VIP number([protected]). It’s been half a month and spent 2 months recharge for absolutely no service and my number is barred.
I want Airtel to pay Rs.[protected] penalty for harassment, inconvenience, fraud and dishonesty.
