Excitel — I have paid for recharge of Rs 2400. Soon after recharge wifi stopped working

Address:

Vijayawada

I have recharged for four months pack. Wifi is not working. I have raised as many complaints and spoken to several executives but there is no response from their end. And I have paid security deposit of Rs 2000 to Excitel they are not returning deposit money either.. There is a pending tickets regarding this issue since 70 days.. it expresses their carelessness and commitment towards customers.
please give resolution 🙏🏻
