Entertainment services charge on phone bill

We have been vodacom customers for ages now and have not had issues. However we noticed that on my fathers (pensioner) phone bill invoice, there is a charge that has been coming off for months of R250, which is labeled as "Entertainment Services" and when I looked, he has been signed up for "ATP Golden pass" at R8 per day! HE DOESNT EVEN WATCH TENNIS, nevermind ever signing up or consenting to be billed. Vodacom please follow up as we need to sort a refund out. You have charged a pensioner atleast R750+ over these last months
