Bharat Sanchar Nigam [BSNL] — UPC not generated on [protected] as there are subsisting contractual obligations

I am trying to generate UPC for migration to another company because my sim is in roaming but UPC cannot be generated because there are some contractual obligations. For this I raised a complaint on customer support on 25 September they said after 24 hours it will to resolved I called after 24 hours because it still not resolved. I talk to the customer support on daily basis but the say same thing daily that please wait for 24 hours after that this will be resolved but it still in obligations.
