Dell India on Tuesday dismissed reports that it was shifting its technical support service for its business customers from Bangalore to the United States.

"No, we are not shifting the work. Dell is committed to India and are growing," a spokesperson for the Bangalore-headquartered Dell India told PTI on Tuesday.

She said Dell had over 2,000 people working at its customer support centres in Bangalore and Hyderabad.

The spokesperson declined comment on reported complaints by its business customers in understanding Indian executives because of differing accents.

Dell, the world's largest PC maker, opened its Bangalore centre in April 2001 and rapidly expanded its workforce to over 3,000 employees.

A spokesman of the Texas-based company earlier said there were complaints from clients, but declined to discuss their nature.

However, media reports said these were about differing accents.

"Corporate customers were telling us they didn't like the level of support they were getting and in the normal course of business, we made some adjustments," the spokesman was quoted by InfoWorld, which specialises in IT news, as saying.

"What (customers) said was, 'You guys have been changing some things and we don't like it as much'," Steve Felice, vice president, corporate division, Dell, told Mercury News.
