My right to choose was hindered by R30.00 different

I have lost my contract phone, however I had an insurance for it. My right to choose was taken away from me because of R30.00. My old device access was R840.00 and the new device that I wanted was R870.00 which is P40 lite, but due to pathetic services I received from kamogelo, zanele and the their team leader grace from insurance side I had to settle to P30. With this high level of pathetic service by the end my contract I will be canceling for good, they have no respect or values for their customers.
