“I understand that my contacts will be uploaded and saved on GalaxyCard, and that they will be used to calculate my eligibility and remind me of my bills.”

Note the use of ‘remind me of my bills’ at the end of that sentence. If this company truly wanted to be clear, they could have written that:

“I understand that my contacts will be uploaded and saved to GalaxyCard, where they will be used for two major reasons. First, they will be used to verify that I am eligible for this service. Second, if I am late to pay my bills, I understand that GalaxyCard will contact my contacts to tell them that I have not paid my bills.”

That is significantly more clear as it specifically states they will contact your contacts if you are late.
