Tata Docomo — tata docomo walky not working

Address:

147001

From 1st feb 2018 all of a sudden my tata docomo landline walky no.[protected] has stopped working. Its showing searching on its display. I went to the local store in patiala city from where i purchased the set and connection. It was closed permanently. I tried to find the nearest store from tata docomo website. Patiala city option is not there in the list. I tried toll free no. Every time its saying that their attendants are busy to attend calls. I emailed the company. Then i came to know that they have barred all the services as they have tied up with airtel. No prior call no sms no email was sent to me regarding this info before barring the number. As my outstanding is already cleared. Now they are suggesting to go to nearest store. While i do not know where is their nearest store. After barring the no. They are suggesting to send sms on 121. How can i sms to 121 while no. Is already not working?
