Mahanagar Telephone Nigam [MTNL] — behaviour of staff

The staff who came to our house to repair the phone (After several months of complaints) was rude and refused to let us check if the wire was long enough. The phone is used by elderly people in the house and needs a wire that is long enough. He refused to work, answer this question and was very rude to the ladies in the house. I don't expect any action from mtnl anyway better to switch to private operators.
