Cab hailing service provider Uber has moved the Delhi High Court alleging its rival Ola was trying to hurt its business by using fake accounts, in what could turn out to be an ugly battle between the two for domination in India’s taxi business.Uber’s case was that Ola set up fake rider accounts and booked rides on Uber platform using phone numbers to which calls cannot be made, according to a source aware of the facts of the case.

“Consequently, drivers wait for 10--15 minutes before cancelling the trip resulting in cancellation charges to be borne by Uber and driver churn,” according to Uber’s petition, the source said. Ola strongly denied the allegations and made counter claims against Uber.

“All the allegations made by Uber in the plaint listed for hearing before Honourable High Court of Delhi are denied in their entirety and we have appraised the court accordingly that the allegations by Uber are frivolous and false to its own knowledge,” according to a statement by Ola.“We can only speculate that this is a counter to the contempt proceedings pending against Uber in this Honourable High Court. It is not beyond our imagination that this is an effort to divert attention from the current realities of the market where Uber has faced major setbacks including the recent incidents of Uber vehicles being seized by the government authorities.

“We stand by our contempt petition that Uber has added and plying new diesel vehicles within Delhi in wilful and deliberate defiance of the local rules and regulations,” it said.Uber declined to comment saying the matter was sub judice.

The latest development comes at a time when U.S.-based Uber and its Indian-competitor Ola have been making tall claims about market supremacy.

As per media reports, Eric Alexander, President of Business in Asia for Uber, said this month that the company’s India unit will become bigger than Ola in less than a month.

“In January last year, we were at 5 per cent market share. Now, we are right at the edge of 50 per cent. I would say that within the next 30 days we would beat them (Ola). We will surpass them very, very shortly,” he was quoted as saying.

Last year, Ola’s biggest shareholder SoftBank claimed that the firm had an 85 per cent market share as of June 30.

SoftBank disclosure was made in a regulatory filing with the Tokyo Stock Exchange.

Uber’s CEO Travis Kalanick, during his recent visit to India, had said that the firm’s market share had jumped to nearly 40 per cent from just 4-5 per cent in January 2015.
