T24 Mobile — barring outgoing service even when having sufficient balance

Address:

Mumbai City, Maharashtra

I am using t24 number since 2015 and had sufficent balnce it in (Rs560) till today but my outgoing services have been barred. Contacting customer care numbers is of no help since almost waiting for gettign connected for 45 minutes and then getting standard replies about monthly recharge policy.
Previoulsy i had recharged with lifetime validy recharge of 1100 rs in 2016. I even top up recharge two months back of rs 100.
Today the balance id 560 min but why call barrign on lifetime validy rechrge.
