Vodacom Bad service and incompetancy

Worst Service Received from Vodacom I received this sms from Vodacom on 16 April 2025; April Red Hot Data offer Just 4 You (NTU): Get 20GB (10GB anytime + 10GB night) data for R99pm. Visit your nearest Vodacom Shop today to take up this limited time offer. T&Cs. Opt out? Dial *135*181#. Vodacom I then proceeded to Canal Walk Century City, Vodacom the one nearest to PnP. I asked them about this deal, the assistant told me that they don’t have that deal. I showed them the message and then they said it must be online, eventhough it stated visit your nearest store. The same time that I was at the Vodacom shop I enquired about a contract I changed from prepaid to contract on 3 February 2025 and to be added to my Vodacom account. I received sms and all the confirmation, but the contract was never activated. The sales person who assisted me was in the shop. The lady checked and sa that he never activated the contract. See the contract that I app**** for as the second snippet. I then proceeded back to the office and called Vodacom online who informed me that they don’t have the deal I must call retention on ***, who treied to help but eventually said I must call *123#. Which did not work as the deal was not on app. I then phoned customer care to complaint, but was told that they don’t take complaints I asked to speak to the manager the agent said that the manager will call me and then I received a call much to my surprise. I was then told that the regional manager will be informed and in contact with me. 2 weeks later no response. I have been with Vodacom for decades and still have the same cell phone number. This type of service is the worst I have ever experienced.
