Where will my help come from?

As from November2017 I am trying to end my policy from Miway. Since then I only walk into walls and no help is offered!! I have phoned multiple times as my phone blocks their calls as spam. The last call was made on 19Decembet 2017 at 8:19 where Christina promised me that the issue is resolved and I do not need to worry anymore and no debit order will go off anymore!! Well surprise surprise! This morning Miway again took ovet R1000 for a policy I tried to cancell in November 2017 already!! What must I do MiWay?? I have moved so I am not residing at that address anymore but I have a home insurance policy that I cannot end?? I want to cancell the policy and and I want my R2000 back!! This is rediculous!
