Transunion **********ly debited my account

I’m so disappointed with this organisation. Going into my account and debited money for some product that I never requested or asked for. Can I please have my money back in my account urgently. I called 3 weeks ago and I sent and email to *** and gave her the proof of the debit order and nothing till today. Now it’s costing me more time and money just to get my debited funds back. The lazy call agent says reason I was debited is that I didn’t respond to communication transunion sent. Do me a favour and don’t ever debit me again. And what communication did you even send that I’m now forced to reply to? If this is not fixed I’m going to ombudsman. There are credit bureau that are free out there
