The Unlimited *****ing Money

Good day. First of all within the last 4 years we have received x4 calls from The Unlimited stating that someone is trying to re-activate a long cancelled subscription with them, and each ti.e it's been said that we don't have any interest and will never have again so they should know the next time. To our bitter suprise we get an sms stating the amount of R220 have been debited from our account(which is not even the one they had when the subscription was active. Also its not even from the main account, it's from a sub account where we put savings). That being said I would like to know how on earth did you get the account details as well as the authorization to actually debit the account. I'm livid right now as I see this as *****ing our hard earned money? Please get in contact ********** 636
