Bad Service from Vodacom

Hello Peter. I just need you to help me deal with the Staff members of Vodacom Protea Glen. They always offer bad service to us customers and I believe they are not well trained for their job. I will talk about one of the bad services I got recently. On 30 April 2019 I went to ask about their sim only deal for Data bundles. They claimed the special is ending the same day I need to go back home to get my ID nd other docs. After traveling more than 30 km they still did not help me upon my return. A lady called Miki took my details and activated my account without giving me any simcard or anything to take home. She told me an error occurred and she had to reverse the whole thing. She promised to call me the next day so that we could start the process afresh. SHE NEVER CALLED me. I called the store the next day only to find that their contact details (as they appear on their website) r not working. They were not updated on the website. I had to travel back to the store on 02 May 2019 to enquire about my status regarding the contract. Another consultant helped me coz Miki was off duty. He canceled the deal for me and told me Miki didn't cancel it. On the 16th of May I got a message on my phone that VODACOM has deducted R310 from my account for something that was "canceled". M getting charged for a service or product I never received, and that is very painful. They are now ruining my credit record and are not willing to help me sort it out. This Vodacom Shop has no good Customer Service at all!!!
