Poor Service Vodacom Woodlands

I were treated very poorly at Vodacom Woodlands by the Manager, assistant manager, and Pat the technical guy We were mislead by the assistant manager when he sold us the Samsung Tablet S6 Lite I went back two days prior and the Manager Joanne said she will call me back Two days later I went back and still no response from the Manager We were also charged R200 twice for the same service Regards
