False information on contract

On the 5th on December I got a call from a vodacom sales lady. She was offering me a vodacom tablet on contract. I refused as I currently am paying R89 on a vodacom contract plus I have pre paid phones. She asked me how much airtime I spend a month and I said about R500 for business. So she says take the contract for R149 and use the free R200 airtime as normal airtime with the contract. And that I can give away the tablet as a gift and just use their discounted airtime. She promised I can still purchase bis and use my airtime as pay as you go on my business phone which number they will transfer the R200 airtime. I received the tablet on the 11th of december. But then they transformed my phone settings also. They took away my caller line ID and all numbers that were calling me was unknown. My bbm and whatsapp stopped working on my business phone. I couldnt even buy bis. I was paying R60 for monthly 2gig data now 2gig data will cost me like nearly R300 which is a loss of R240 against saving a mere R50 airtime. I cancelled the vodacom table the same night on the 11th December 2017. 8 Days have passed and still they havent collected their tablet. They even debited me an amount of R296 even though I cancelled the tablet. They said that my phone will go back to normal pay as you go only after they have collected the tablet which is just not happening. I even had to buy a replacement phone for R600 because whatsapp and bbm stopped working on my business phone. Plus my caller line ID they switched off so I missed many calls from clients and couldnt return their calls as I couldnt see the numbers calling me. Vodacom is a ********** company, I have called their after sales many times but they couldnt tell me when they are taking their tablet back but very fast they successfully debited me for nothing. Their sales lady has **** about many things and sold me the tablet. For their greed they will lose about R500 from me a month as I will port my number to another network. Just for R149. Vodacom is very unprofessional and *****y I will never deal with them and I will tell many people as possible never to take vodacom contracts . They are a waste of my time and money.
