After Sales support highly lacking

On 10th Sept 2022 i took out a Data Contract - Sim only with Vodacom - Gadget Fix Oakfields, Benoni. After 3 days, i was still not able to connect to the Internet. My phone connection kept stating Connected without Internet. I couldnt access the Internet on my laptop either. I went back to the store and the young technical lady advised it was because i disconnect from the Internet. She also said that when i get the message connected without the Internet, i must take off the cover, the battery and slide out the sim card for a short while and then put them back together. This i was doing up to 3 times a day. They also provided me with a whatsapp number to query anything i needed to. Howver, it takes them 2 days to get back to you. Nowhere in the quote and or contract documentation or in their booklet do they give a full call centre number for Vodacom. Eventually i obtained the number and phoned the call centre. I explained the problem and Thabiseng - Ref 005D0341BE advised that he needed to activate the Internet Settings. I then asked why the store did not do this and surely they should. His reply was an immediate "No". I was shocked at this response. So i sat without data access for a week and had to do the work to get it sorted out. Vodacom, you are good at selling your products, but you after sales support is highly lacking. Not a good start to a relationship with yourselves.
