The rebel group, demanding better playing conditions from the All India Tennis Association, said they will continue to remain unavailable for Davis Cup selection until the federation engages with them in "good faith".
The group also got bigger, as Jeevan Nedunchezhiyan, N Sriram Balaji and Vijay Sunder Prashanth joined in, taking the number of revolting players to 11.
"We are disappointed to note that instead of engaging in discussion with us, the AITA has selected an inexperienced team to represent the country in this crucial Davis Cup fixture," a joint statement from the rebels read.
"In making each of our suggestions to the AITA, we were guided by our strong convictions regarding what we believed was fair and beneficial to the future of the sport in the country and are dismayed to hear that the AITA has labeled our suggestions unfair and unjustified.
"The AITA's position reiterates and reaffirms our stand, and we are constrained to state that, unfortunately, we will be unavailable to represent the country until such time that the AITA engages with us in good faith.
"We wish the Indian Davis Cup team that has been selected for the fixture all the very best," the statement added.
AITA claimed that it had accommodated more demands of the players but they still remain unavailable.
