Telkom unexplainable 'Event Billing Charges'

Please note that Telkom mobile has subscribed me for "event billing usage" for a company, which they cannot identify when and how I subscribed with from December 2020. This subscription amount are above the R199 deal I signed up for and are going up every month. I have asked Telkom to cancel these subscriptions previously to no avail. I need Telkom to advise soonest from their side, as this is impacting my pocket negatively, and I would like to have a full refund on the amounts that I have paid. This is very ridiculous, if Telkom cannot help me resolve this issue, I will have no choice but to cancel the Smartbroadband 20G wifi deal of R199 I signed up for.
