Appalling Vodacom customer service

I went to Vodacom shop repairs in Sandton City to upgrade my son’s contract using their Black Friday deal. They told me to start the contract process that day, wait 7 days for stock and complete the process when the phone arrives. I went in store on 19 December 2022 to check if stock had arrived as they did not contact me as promised and they still had none and said they would let me know when it arrived. I went back in store on the 3rd January this year and they told me that the stock had arrived however the deal expired 28 December 2022. I asked them why they hadn’t contacted me to let me know stock had arrived and Nebraska, who I spoke with in December said she had been off at the time the stock arrived and that she would email her regional manager to authorize the Black Friday deal as I had already started the contract process while waiting for stock. Last week I was told that I would get the phone and complete the process by Friday, but this did not happen and again, no communication from their store. I was in their store today to follow up and I’m still waiting for authorization for the Black Friday deal by their regional manager. It’s almost 2 months since I started the process for the upgrade and Nebraska seems to be at a loss as to what is happening with the authorization. She keeps telling me she’ll send an email but nothing has been resolved. Vodacom your service is appalling and this is not the way you should be treating your customers. What a disappointment!
