no response from Vodacom regarding travel saver subscription.

Hi Vodacom, to date no one has contacted me regarding my original complaint on the 3rd Feb 2020. the complaint is regarding your travel saver subscription which I was notified of each day via SMS while overseas. I had to contact your call center on the 6th day telephonically from my mobile as all attempts to de-subscribe failed, this call cost a fortune no doubt. your call centre agent informed me that I had activated this service in 2017, this is nonsense, since 2017 I have been overseas 3 times and not once was I informed on travel saver charges or have been billed, only this time. secondly I would never subscribe to this service as it doesn't make financial sense to be billed R30/day if you are not making at least 20 minutes worth of calls per day, the offer is misleading to say the lease, I would like proof of my knowingly activating this service. I expect to be credited all charges for this service since the 1st of February. please be advised if I do not get a response from someone at Vodacom regarding this, I will be presenting this as a complaint with the NCC.
