Difficulty in resolving ***** matter with Vodacom

Vodacom debited my bank account for a service I never signed up for. I called the call Centre. They mentioned a new contract had been signed up online. I informed them this was not me. Was told to send in various documents for the ***** department to look at. That was sent on 3/10/2023. Received confirmation of receipt of my email and a note stating to wait 7 - 14 days. Sent another two emails to follow up to no avail. Call centre can't help with ***** dispute. No other avenue to follow up as you can't call the ***** department. Very frustrating when this is an error on Vodacom's side and its now costing me my time to force them to take action. It's impossible dealing with such matters with Vodacom. You can't get hold of anyone who can help. and senior management email addresses are not available online. The actions or lack thereof, is disrespectful of one's time and a lack of interest in resolving what I consider to be a serious matter. There has been not one call or email/no communication from Vodacom whatsoever on the matter. Now reported the matter to Icasa in the hope they can get Vodacom to act.
