Thank you for reaching out to Zebit regarding your account. We re-evaluate the performance of accounts on a 3 - 6 month basis and may increase your ZebitLine. Payment history is important in our evaluation of your ZebitLine and late payments may prevent you from getting an increase. So once you make a purchase, please remember to sign-up for auto-pay so you do not miss a payment. For example, a Zebit line of $150 could grow to $400 in 1 year with regular payments against a set of purchases. Outside of those reviews we cannot increase an account. Regrettably, I am not able to give you an exact time-frame that your account may be reviewed. However, I am happy to notate your account so when the review team does come to your account for review they will be aware you are interested in a Zebitline increase.
