BILL DOUBLED after limit request

My Vodacom bill drastically increased to almost double, the month after I asked them to place a usage limit on my contract. After contacting the call centre they blamed my children for using my device without my permission!!! After the SECOND month of doubled bill I cancelled the account.<br> <br> I have since moved mine and my two boys' contracts to another service provider<br> <br> The exact same has happened to husband's bill after he also placed a usage limit- and there too they blamed my children!!! He has now been advised that he cannot cancel his contract until after the 6th of the month!<br> <br> Shocked & disgusted!!!!
