Disappointed Loyal Customer!!

I have been a loyal client at King Price for the past 5 years and never have i experienced such shoddy service to say the least. On the 26/08/2018 i received a letter from King Price advising me of the imminent increase in October 2018. I had a few changes to make to my policy so i decided to call them a day later (on the 27/08/2018) to advise them of this. I called and removed 1 x household contents to be effective 01/09/2018 which decreased my premium to R762.83 at the same time i requested that the night time parking for my vehicle be changed also effective 01/09/2018 , i was informed by the agent assisting me that he was unable to make future dated changes for the parking and that i should call back in September. I called back on the 04/09/2018 and changed the night time parking and my premium further decreased to R749.96. I clearly asked the agent to confirm if this would be my premium moving forward and confirmed it would be , he also advised me of a credit that is reflecting on my account due to the changes that were made. At no point did he inform me that the increase will still be in effect even after i probed . Funny thing is King Price debited the correct premium at the end of September but app**** the increase in October with no prior notice I called their call centre on Saturday 27/10/2018 and was assisted the agent informed me that she can see that there is an error with my policy she would escalate to IT and provide feedback by Monday (29/10/2018) , Monday came and no feedback was received. I received a call on Tuesday to state that IT is still working on my enquiry. On Wednesday i received a call from the same agent informing me that the charges were correct. I challenged this as according to the call recordings this is not what i was informed. I asked for the calls to be listened to by a manager and for feedback by close of business yesterday (31/10/2018) I was immediately informed that it takes 48 hours to retrieve the calls , i informed the consultant that if i did not receive feedback by close of business on the 31/10/2018 i would be posting my complaimt on Hello Peter... still no feedback received!!!
