Airtel — service barred for no reason

I team,

I have been writing this email to you with regards to my postpaid account. Initially i received a notification from airtel stating there are payment dues with previous operator and if not paid services will be disconnected after which i have made the payments and emailed the details to both my previous operator and airtel. However looks like both the service provider doesn't understand the concern the email was sent with. Anyways payment was made on 10th feb 2020 beyond which on 21st feb the service was barred. When called up airtel customer care i was told to visit the store because customer care don't have the bandwidth to make the changes.
I reached out to store at hegde nagar and the store manager was kind enough to understand the issue and get all the details on some portal and assured the service would be resumed in 4 hours following which my service was resumed.
But again on 22nd feb i received a notification from airtel on barring my outgoing calls for payment due with previous operator, following which i called up airtel customer care and i was informed that there has been an error and service was disconnected. And supervisor from airtel customer care assured of restoring service asap. It has been almost more than 8 hrs but my service or outgoing is still not resumed.
Is this a kind of joke? Is airtel trying to make fun out of customers. I have missed important calls because of this and who is taking responsibility for this.
I'm tired of contacting and visiting airtel store.
