hi there ive jus tried to use my vochers comet told me the same thing iam going to write to the address on the back of the vochers but explain this i was given vochers by comet to use whenever in the future so what has kingfisher or woolworths got to do with it i dont care who, what, why jus that comet should giv my money back as they issued me with the vochers.if i was advised that the other 2 companys have the real right over the vochers i mite of thort twice.i cant go back to woolworths coz all stores in my town are shut.comet took my address at the time they issued me with vochers why not write and tell me they no longer aint getting accepted customer service.worst thing is the sales adviser wasent even bothered when i got upset that i was going to lose £80 quid how patronising.
