i called CSP customer service 1-(800)-297-5578. the agent on the other end sounded clueless. these were the 2 questions i asked
1. When does this offer end?
"i can't guarantee anything on my end"
2. if I added an AU to my CSP, would that person still be eligible for the sign-up bonus in the future if s/he were to apply for CSP as the main cardholder/applicant?
"the AU would be reported to the credit bureau and their eligibility would determine whether they are approved for the CSP card"
anyone know the answer to these questions? i'm gonna call in tomorrow morning to get better answers from another CSR.
