Right after you quit paying your credit cards, you will receive numerous collection calls. At first they will be somewhat few, and then as each week and month passes without payment, the calls will increase. Remember, if the person calling you is not from a collection agency, they have the right to call you during most hours of the day and night. However, most credit card companies are still respectful and choose to call during the hours of 8 a.m. to 9 p.m. You will also receive letters in the mail about your debt and maybe settlement offers. In addition, late fees and any over-the-limit fees will accrue on your balance in addition to any existing fees and interest rates.
