Hi there Chelc999,
Welcome to our Community Forum and thanks for posting. Regarding the Refer a Friend, can you tell us whether the correct process was followed? It's important that they follow the instructions and use the links so our system knows that the Refer a Friend process is being followed. Please see this link for more information. If it was followed, it may be that it's too soon for the credit. Please refer to the above link about the timelines.
Thanks,
Lisa
