We had a phone call from a company called POWERKEM, selling hand cleaner,price quoted £17.90 per tub which is around the price we usually pay.Approx six weeks later 2 tubs arrive we open one try a handful and find it not as good as our usual suppliers, so we sealed it back up.The company called for payment I hav'nt recieved an invoice so I asked how much we owed them the total amount being £300.45.So i said of course your joking would you pay £300 for 2 tubs of hand cleaner this as got to be wrong, she said she would speak to her manager, i told them i'm not paying come and take it away.The tubs contain 15L of cleaner so we have 30L of the S..T They seem to have targeted some other bosch garages, so i wondered if anyone else as had this problem, i am contacting trading standards but who needs this hassle.I have today recieved a final reminder giving 7 days to pay or it will be referred to their solicitors the usual costs plus 3% per month.
