Mahanagar Telephone Nigam [MTNL] — made the payment but still our phone line we are getting msg bill not paid

Address:	Mumbai City, Maharashtra, 400052

Respected sir /madam,

The phone line 26041412 is not working since yesterday. We are getting message that we have not paid the bill, whereas if you check we have made the last payment on 27 jan 2018 which was before the due date and for the current month the due date is 28 feb 2018. We have received the bill yesterday from mtnl.
Don't find any reason for you to disconnect the line. Every month we have to give a written complaint as the line is disconnected due to which our swipe machine also stops functioning and we face a lot of problem in accepting the payments. For your reference our docket no. Is 3235 which we had registered last month.
We run a activity center, the phone line getting disconnected every now and then creates a problem in our day to day functioning.
I would appreciate if you can resolve this issue asap.
