Cancellation and professionalism

I have app**** for two policies with affinity health I only received one. I tried cancelling my health plan the beginning of March 2019 and just got a mail to say someone will call me back in 2 days, no one got back to me I then sent another mail stating I want to cancel this health plan, still no one got back to me. I think I have been lenient enough now,but I have been waiting too long for someone to call me to cancel this plan. I also feel that the staff that called me to sign me up was not professional because on several occasions they've called me talking and singing in the background.
