Bad service

have been trying to get a prescription letter from getbucks since the 8th June of for an account that's over 5 years old. They keep telling me they will call me back as getbucks department is busy and when I asked direct number they told me they don't have direct number and email number . When i email they ignores me and when you call they don't answer. I've been calling every day and am not being answered . I am really concerned.
