Theft

Good day I just want to query about my airtime. I loaded airtime and it was deducted for the subcribtions that I do not know. Recently (03/07/2019) I bought airtime for R33 and R15 was deducted this happened several times, last week I phoned and spoke to a consultant Zimkitha regarding the cancellation of the said data subscriptions on a nokia 105 nog al, and today I spoke to Bongiwe with the same problem. I thus request for a refund on particularly on mentioned subscriptions. This is theft and it has been happening several times
