Vodacom and it's ****s

I'm so disgusted and very disappointed with Vodacom, I got a call from call center offering me data and I explained that the account is in my husband's name and then my husband gets a call and don't agree to the contract the next thing the contract is generated without our knowledge, we get a wake up call when we are being served with a bill then we complain about the contract and they promise to cancel it, wr got cancelation messages and all but my phone wad then blocked because I'm owing Vodacom... I'm so shocked of this kind of incompetence cause it's messing up with people's credit records I wish people would just be careful of this sales seeking and unfaithful sales.
