Unacceptable Treatment by MiWay

Received premium increase for this year and my overall premiums have gone up by R576.48. I phoned in just now and spoke to a "David" and asked why my premium has gone up so much considering that I have not claimed for either of my 2 vehicles since I've been with Miway. I asked David if there was anything he could do to retain my policy with Miway to which he said he needs authority from his Manager, put me on hold for close to 10 minutes then cut me off... I also emailed MiWay last week with the same query, got a "read" notification to my email on 7th of January at 14h33, but no response. This is not acceptable. I mean, is MiWay trying to get rid of me as their client? Sure feels like it!!

My policy number is ***4... if anyone at MiWay cares enough to get back to me with an answer!!
