Double billing

I signed up with a Pastel subscription in Oct 2024, spoke to an agent and realised it's not the correct programme, moved over to Sage Online immediately without using Pastel. I am still being billed for BOTH packages. Koketso Mokgatle simply ignores my e-mails and hasn't sorted the issue out. I have been following up monthly, I cancelled the debit order, but they payment still goes off. Absolutely ridiculous!!
