Hi,
You have send me the bill for reliance communication which is already suspended your service in Mumbai. I have already paid for the service I used back on I guess on November 2017. I am sorry to say this that I am not liable to pay any of the services you never offered me. The number I used for all my bank transactions and everything was gone without any of the intimation. Thank you for your worthless service and I wont pay for something which doesn't even work. If you have something to say you can contact me on this email address because the number doesn't work and if you really want to communicate. I don't understand how can send me bills when you are already closed your services for post paid ? I couldn't even get incoming calls in that phone because there was no network.
Thank you but no thank you for your unavailable but billed service.
