Phil,
I agree with Dick.
The statement should have pointed out that a maxium credit limit was in force. I'm not wanting to bicker about the wording of the credit freeby but I read it as saying you will continue to earn credits until you miss a day. Since I am not good at 'reading between the lines' I take these type of statements literally because lots of the times it's difficult finding the person who knows what he meant.
The same type thing occurs with the 'free' credits offered for taking a survey, watching their sales pitch, ect.
Each of those offers state very clearly that the credits will "confirm instantly". If you click "missing credits" you are told that 30 minutes may be required. OK, makes sense. What doesn't make sense is the efforts involved in finding answers after not receiving your credits at all. And I'll also state that when you spend 45 minutes answering question after question you might not feel you are getting a 'freeby'.
I think the old saying was and still should be; "Say what you mean and do what you say".
