BSNL - Kharagpur

Customerat BSNL Kharagpur is really horrible. Lodging complaints at Call Center or through website is almost impossible. Even email complaints are rarely taken care of. Two tier grievance redressal is a farce here.
1. Without my condsent/ information, by Broadband paln was changed midway (after taking one-year advance rent) and all usage started to be billed-- dozens of complaints failed.
2. Even after getting confirmation about free- night-calling between 9 pm- 7 am, for a full month all such calls were charged- little redressal just offeredd after long delay.
3. Suspicious billing for Rs 111 was charged for phone calls in bill for July 2015- no redressal so far.
4. My phone, Broadband was out-of–service from 7.7.15 to 14.7.2015, 04.4.15- 15.4.15 , 21.4.15- 27.4.15, 30.4.15 -01.5.15 rent rebates HAVE NOT YET BEEN GIVEN.
5.For over 2 years I am not getting printed bills for my phone- 03221256084-- no action in spite of repeated complaints
