B&H Blue Switch - Horrible tatse

I have been smoking Benson & Hedges Blue Switch for about a year. Since December I have purchased numerous packets that have an absolutely disgusting taste. Either some kind of berry taste has gotten into the cigarettes or something has died and that sweet rotting taste is in the cigarettes. It is absolutely disgusting. I only ever purchase my cigarettes from Checkers / Pick & Pay in Canal Walk shopping center and have had the same experience. I have tried it a few times since, but I am sitting with boxes of cigarettes that all taste the same. It is an absolutely vulgar taste and I actually feel ill when smoking it. My friend purchased hers at Checkers at Cobble Walk and had the same experience. Will NEVER EVER buy this again ... know it is not like they care as they are all the same company essentially ...
