SPAM and HARASSMENT from MiWayLife

A few months ago I concluded a quotation for car insurance with MiWay. As part of some promotion, I was given free life cover for a period of time. Something that I do not want nor need. As a result of this, MiWay has been calling me relentlessly on my cell phone presumably to try and sell me more of their products or extend this cover to the extent that they have filled up my voicemail box. I want to be clear, I do not want or need any MiWay products. Should MiWay continue to contact me through any medium I shall institute legal action against MiWay for harassment and report MiWay to the relevant ombudsman with all costs for MiWay's account. I hope this clarifies the situation for MiWay.
