Discovery Premium Quote - a sly trap! Beware!

Last year I was contacted by a Discovery Agent promising to under quote my current Insurer. At first I was doubtful but - turned out they did. The call centre agent told me not to listen to the other company when they tried to tell me that the competitive rate was just a ruse to attract me. Turns out OUTsurance was was to Dicoverys ploy as one year later Out of the blue I get a letter saying my premium is going up by 35%. Shame guys who would have thought the mighty discovery would have to resort to cheap tactics like that. Borders on misrepresentation!!
