Miway Life Competition Continued Unwelcome spam phone calls

I am a Miway Insurance client. Miway Life is apparently running a competition and has decided to call me EVERY SINGLE DAY for 3 weeks, always a different telesales agent. I have told them I am not interested, I have asked them to stop calling me everyday, and yet now, again, at 6pm they have again called me after I asked them yesterday again to take me off their call list. I am utterly furious at their lack of respect for their clients and will be calling around tomorrow to get insurance quotes elsewhere, if they feel that because I have one product of theirs they can then harass me daily with something I am not interested in! How disappointing.
