Citibank Credit Card Complaint

Citibank Credit card department,

APR or interest rate Missouri

The Home Depot offers consumer credit cards which are serviced through Citibank ( citiretailservices ). They periodically offer extended terms offers of no interest for six, twelve, eighteen, or twenty-four months on purchases of various amounts. I find that the deferred interest charges are being accumulated in an amount that exceeds the rate that is in the account agreement and that appears on the monthly statement. On my -/-/2016 statement, the deferred interest charges increased by $23.00 on the $1100.00 promotional balance and by $61.00 on the $2400.00 promotional balance. When I calculate the 30 days interest at the published 25.99 % rate, I get $22.00 and $52.00, respectively. I am attaching copies of the -/-/2016 and -/-/2016 statements.
