Bad service

I have not used Optipharm since 2013, and am no longer on the Medical Aid which was affiliated at the time. I am still getting the sms's to send thru a new script, and have phoned the call centre on numerous occasions to cancel this message. I hold on forever and then the call is dropped and I have to start all over again. If I remember correctly I stopped using Optipharm because of their inefficiency and seems nothing has changed over the years. Please contact me to remove my details from your system for once and for all.
