Ide Enterprises — Ifb washing machine service

I called ifb official site and called toll free number for service.A person came and inspected the washing machine and said suspension and switch need to be changed.then he quoted 3000 rs of which 2000 has to be paid in advance.since I need a speedy repair I paid 2000 and he said he will come next day.Then I asked a friend to know about the cost and he said suspension costs 450 only but the enterprise charged 2500.Then I called them and asked to cancel the service.They were reluctant at first and then said service was cancelled and money will be refunded.But money was due almost for 20 days.I called them daily and on a daily basis they assured me to return the money but they didn't.aI even went in person but the address were nowhere to be found.I think they're frauds.
