M-web *****ed ******...

Today my husband was debited a R1500 +, by m-web, for wifi that we dont have, never received, canceled application in November 2018... No contract was ever signed, no copy of ID, proof of address, and all the fun stuff that go along with a contract, was ever provided. So please could someone, please advise me as to how m-web can debit someones account, if there was never any service provided?!
