This number (090888) is used by Insurance Services, owned by Royal Sun Alliance and appear to be the debt recovery side operating out of India.
Others numbers Royal Sun Alliance have used over the past few days are, 0016056 & 000-701-2212212. The India side of their debt collector company in India can be contacted on a UK number 020-833-81021.
Hope this deters you from doing business with Royal Sun Alliance who have not assisted with my complaint in any manner.
