Multiply membership frustration

I am extremely frustrated and angered by the way my multiply membership has been handled. I joined Multiply in September to be active 1 October and then called the call centre and changed to Provider option.I was told that the cancellation can be done on their side and that i needed to complete an application again for Provider which i did. I again called 1st week in December to find out about the nu metro benefit only to find out my membership was not active. The guy then spoke to his supervisor who then sorted it out and i was advised that the 1st month is free and billing would start the next month .I have since called and added my pick and pay smart shopper , etc and today when i called to find out about another benefit i am told that my membership is not active, it was never changed to the provider benefit and this is now 3 months later, after speaking to several contact centre agents regarding my membership, after receiving my card and welcome email and now nobody can explain whats happening and i now have to complete another application form. I would appreciate an explanation that makes sense please as to why i now would need to complete another form and why after all this?
