Terrible service

Writing this in disappointment. I’ve been sending cancellation emails to spark since the 2nd week of January without any feedback. When you call their line you’re caller number 30 and wait for about an hour before someone actually answers my call. After waiting that long I get told that I’m through to the wrong department, when my call gets transferred it drops off. Spark School owes me a refund and yet have the guts to debit my account and my child doesn’t even attend the school. So now. Can I please get some traction on this. Starting to lose my mind.
