Handed over to legal but I’ve canceled

I was contacted by vodacom for a data contract and it wasn’t what I was told it would be. I went to 3 vodacom branches to confirm what I can do and they advised me to cancel. I then canceled immediately and received confirmation that it has been canceled. They debited my bank account and I reversed the debit order. Now I’m being handed over to legal. I tried to phone vodacom numerous times and I couldn’t speak to anyone as it’s impossible to get through to anyone. My credit record is effected by this. I will contact the ombudsman and lay an official complaint. I have rights as an consumer.
