Contract changed 2 in one year without my permissi

I am very upset twice has my contract been changed without out me giving permission. First time i was moved to a Top up 200 this issue was sorted out 7 months later after speaking to management and being cut off numerous times. Second time November I was without a phone for 2 weeks because Vodacom changed people contracts and i couldn't even phone customer care and had too phone from other peoples phones.<br> <br> I went to a Vodacom shop where they informed me that it was my sim card, I did a sim swap and they new sim did not work that I payed R140 for they then did another sim swap after one week i went from the technical department to the engineers department where at the engineers department one week later they informed me my contract has been changed that was why i couldn't use my phone. So i wasted 140 non refundable at vodacom and was left again for 2 weeks without a phone. My upgrade was 5 January where i have informed them to cancel my contract immediately because we don't have any signal where we live and in the whole area and they havent came back to me regarding signal just told me they will put a box in our house to strengthen the signal at an addisional fee on my contract
