Disgusted service

So beginning of June me and my husband went to Vodacom The Grove mall in pra for an upgrade on an iphone 8. Days after we were told we already upgraded to a samsung S10 at Cape gate mall for R900p/m. We stay in pta for heaven sake. My husband went to the store in the grove and they showed him that we upgraded and showed him even the ID document (of which was *****, the picture was not his and the issue date). We logged a ***** case with Vodacom. Later that month as I was following up they said that the case was closed and it was indeed ***** and they even made sure that the debit doesn’t go through. So now this morning we wake up to a debit order of R905 from Vodacom. What the hell is going on Vodacom?! I am really disgusted in your service.
