I don't have Rain account

I don't have a rain account and I never opened one before, my family members are not using Rain wifi, I don't even know anyone that uses Rain wifi. I noticed in December that R649 was debited from my capitec bank account. I sent an email to my Capitec bank and got Rain email from the internet. I got the case number from Capitec but Rain never rep****.

Called Capitec bank to follow up and I was told that Rain has debited 4 times on my account and that they are still investigating. But it's long already.

Kindly assist, I want my money back as soon as possible. This is ***** and it's done to the most vulnerable being.
