DISAPPOINTING SERVICE

I have been holding for 17 minutes and I think this is unacceptable. I am on the essential smart plan and was told today I can only make one pharmacy change a year. I accidentally on the app chose Clicks instead of Dis-chem ( my script is sitting at Dis-Chem), and now I cant change it. The consultant had me waiting for 17 minutes. I eventually had to put the phone down because that is ridiculous. I didn't choose Discovery to have this kind of service. Help me!
