Amending policies without full consent

I opted to cancel cover on my vehicle with dial direct due to another insurer offering better coverage for more or less the same amount as what i am paying now, spoke to an agent yesterday and then she tells me that my other policy for home content cover has gone up by almost R200, when opted why i get told that when i cancel a policy the discount falls away. This was not once discussed to me and my home content cover was effective a couple of months prior to me adding my vehicle. I never accepted this and our phone call got cut, no attempts were made to get back in contact with me only received a polocy amendment email of terms and conditions as well as the new debit order amount to which i have not agreed. I feel that my cancelation of the one policy should not affect my first policies premiums in the effent that i do cancel. Should i not hear from dial direct by tomorrow close of business as keep in mind it takes them 3 days to return calls i wil lodge this matter to the ombudsman,
