My land line no. is 25333104 and CA no. [protected] and bill no. MTDL[protected] dated 09/05/18. in the name of Vinod Kumar Saxena. has charged Rs. 900 as miscellaneous charges while I have not availed any other services except telephone call.
may be it is internet accessories charges which has been charged when not deposited it. But it has been deposited by us in last week of May 2017.

may be it is entered in system by MTNL department. kindly may arrange to check it and return miscellaneous charges and intimate to us.
