Terrible Service

A week ago I gave a 5 star rating due to being assisted with a lower premium. I have been trying for over a week to get my physical address updated on the letterhead.The vehicle cover address is correct. Each time the agent says my address is updated and then it is not. I need it for FICA purposes. Suddenly my premium went up again. The agent I am talking does not seem to understand the issue with the adress or MiWay system is not working. My policy has now been escalated as they cannot understand why my premium has increased again. The agent Kaglamelo. I am extremely disatisfied with the service.it is very frustrating trying to explain the same matter over again. If do not receive a satisfactory response by Monday I will consider leaving Miway after many years. If they cannot do something as simple as changing an adress, I dread to find out if I ever have to claim for someting. I need the issue with my premium sorted out as soon as possible.
