Vodafone — Not allowing outgoing calls from phone despite full charge

I relocated from mumbai to dehradun in september 2019. The service provided was hassle free. Consequent upon recharging for 1 year from 2 April 2020 to 1 April 2021, I started noticing from May 2020 the outgoing calls were barred. I continued making complaints. Sometimes for short periods I would be allowed roaming facility but to face the problem again. I am now facing this problem from August 2020 and the company is not allowing roaming despite repeated requests and complaints. If I port to UP circle, I will loose the entire amount of recharge.

I may please be allowed roaming immediately and also additional periodicity of the recharge to cover the period when this service was not provided.
