Just stop Phoning me please

I was looking for new insurance and gave MiWay a call. All good and well. They did not give me the best price so I go somewhere else. Three months go by and they phone me once a day for three weeks. I will never do business with a company that does not respect NO. Stop phoning me. And the excuse of i am a sub contractor and do not work for MiWay does not work. you got my details from Miway.
