Crime scene cleaners

I was diddled big time by Kleenbin - see my previous review. I paid for TWO months and cancelled when they overcharged me for the SECOND time - I cancelled the service IN WRITING and now I have received ANOTHER EXORBITANT invoice for NO SERVICE - ie I CANCELLED the service yet this month they have billed me again DOUBLE despite me NOT USING the service for the month and despite my complaint that they stole my money in January and February as they charged me DOUBLE both months - WTAF
