Republican presidential candidate Donald Trump has used fake Indian accent to mock a call centre representative in India, but at the same time Trump described India as a great nation. The billionaire said that, he called up his credit card company to know, whether their customer care is based in the United States or overseas.

Trump said  his supporters in Delaware, that, "Guess what, you're talking to a person from India. How the hell does that work?"

"So I called up, under the guise I'm checking on my card, I said, 'Where are you from?'" Trump said and then he copied the response from the call centre in a fake Indian accent.

"We are from India," Trump impersonated the response.

"Oh great, that's wonderful," he said as he pretended to hang up the phone.

"India is great place. I am not upset with other leaders. I am upset with our leaders for being so stupid," he said.

"I am not angry with China. I am not angry at Japan. I am not angry with Vietnam, India...all these countries.

"Trump mentioned the fake call to India during his remarks on what he described as "crooked banking.

"Delaware, is a hub for the  banking and credit-card industry in the America. It include Bank of America,  M&T Bank, Citibank Delaware and PNC Financial Services Group.

"They are making a lot of money," Trump said.

"You can't allow policies that allows China, Mexico, Japan, Vietnam, India. You can't allow policies that allows business to be ripped out of the United States like candy from a baby," Trump said in his address.

"The manufacturing jobs are being stolen. Our jobs are being taken. We are losing at every front. There is nothing good. Our country does not win anymore. The jobs are being stripped. Factories are closing. We are not going to let this happen anymore," he said.

The Republican presidential primaries is scheduled in Delaware along with several other states on April 26.
