He also hit out at party's MP Bhagwant Mann for allegedly "engineering" his replacement with his "close friend" Daljit Singh Sadarpura.
"The party replaced me as it wanted to nominate a rich candidate," alleged Sran who joined AAP in 2013.
A doctor by profession, Sran said he was not informed by any party leader about his replacement. "I came to know about it through my volunteers," he said.
"I have already covered 55 villages out of 151 and listened to the problems of farmers in 25 grain markets," he said, adding, "My campaign was not poor or listless as described by the party".

He accused MP Bhagwant Mann of adjusting his close friend Daljit Singh Sadarpura on this seat. "Everybody knows that Sadarpura does not belong to this constituency. He is an outsider," Sran claimed.
When asked whether he would take up the matter with party's national convenor, Sran said, "Arvind Kejriwal knows everything."
He said if the party thought that his campaigning was poor and weak, then it should have provided support by mobilsing more volunteers to boost his campaign.
49-year-old Sran, who has been running his hospital at Dharamkot and holding free medical camps, said when the party had announced to replace him with another candidate then it should refund the expenses incurred by him on the campaigning.
Yesterday, AAP had announced replacement of Sran with Sadarpura, who is a progressive dairy farmer, saying his election campaign was poor and declining.
Sanjay had claimed that Vinod was not "working hard" and his campaign was going on a slow pace which was why he was replaced.
