****** again!

I don't understand why Momentum is always robbing me. I cancelled my membership with them in February, following the bad service I have continuously been receiving. They don't answer phones, they don't respond to emails and when they do, they don't attend to the pressing matter. So my last debit order ought to have been March. This morning I wake up to a debit order again yet they even emailed me that the mbership has been cancelled. I don't owe them anything at all.
