CONSTANT HOUNDING FROM MFC

Please could I kindly request that MFC stop constantly calling me every single day offering me products. I dont mind the odd call but every single day as well as calling me on my work number, I did not give permission. It feels like MFC is abusing my personal information by using every single channel of communication to hound me. When you politely advise the agent, they suddenly become rude. Please review who last called me and it will be there
