Gordies Bins is a fairly large rubbish collection firm in Wellington. July last year they were bought by a company called "Waste Management". Around that time they stopped doing fortnightly pickups and moved to weekly, however the communication around this wasn't clear - we had no idea it had changed to weekly pickups and payments. They had a direct debit, and they started billing us every week instead of every two weeks - I'm not sure if we ever actually agreed to this, though they tell me they sent me a letter. We kept putting bins out every two weeks. It was our mistake, and we should probably check the bank more carefully, but it's relatively tiny amounts so slipped under the radar. I'm not going to pursue it, it's too little money for the hassle.
My main point: anyone using Gordies Bins (or any other service really), make sure you know what you're paying and what the service is.
I asked Gordies if they'd give some kind of a "good faith" credit for a customer who'd been with them for probably 5+ years. They said no, they weren't at all sympathetic, so goodbye Gordies.
