Terrible service from Miway Insurance

I am really disappointed with the calls that I received from Miway today, I have been a client with them for many years and today I got a call from a rude agent and especially the way they explained to me. so I had an incident where my drivers window was smashed, I paid an excess of R1350, the lady calls me to say my premium needs to increase due to the fact that I claimed, Miway has combined all my claims to say i am claiming a lot and that is the reason for the increase, That is wrong because in April an increase was done. I mentioned i would cancel the insurance, she asked okay from when will this be done, is that how you speak to a client for many years, is that how Miway is trying to retain customers ??? what am i paying a premium for. I need to be afraid to claim for an increase, this is absolutely ridiculous. The 2nd lady tells me you'll are running a business, since when have you taught your staff to speak in that manner to customers, I work in the sales industry and this is not how you speak to clients. I am absolutely disappointed and I will be checking around for other quotations!
