Voda. Con , dishonest, not transparent company.

Vodacom Liberty Mall , I purchased 3 phone contracts for family and a data contract. I received a phone call from Vodacom saying my daughter doesn't use her airtime but converts it to data , would I like to change her plan to just data , I said yes , they said for an additional R49/ month they could provide 50 GB day 50 GB night , I agreed , turns out they were conning me , through clever wording the phone which was due for an upgrade was being replaced by the data , so when I enquired about firstly the upgrade of the phone and why I was still being charged for the phone since the 3 year contract had expired ? 5 consultants , two managers later I heard every excuse lie under the sun . They in affect changed the phone upgrade into data through dishonest non transparent and honest explanation. I was promised a senior manager would get hold of me by phone or email by the end of the business day . Another lie . Seriously considering opening a ***** case against them .
