Premium increased by 50% on Business insurance

I am very very unhappy with how Miway is treating us as a client. Where have you ever seen premium increase by 50%? You get customers to join your company with a good premium and after a year you make it unaffordable for the customer. I really don't think this is a good business practice. We were really deceived by Miway. I have never ever seen this before. Premiums generally increase by 6/8%. Kindly adjust my premium to an acceptable amount. As current premium is not acceptable. I will never recommend Miway to anyone. If this is not changed I hope everyone reading this post can note what kind of treatment you give to your customers. I have personal insurances with different companies and was considering moving them under one company. But I see how Miway is. Very deceiving way of doing insurance.
