The FCC said the decline in wireless customers complaints for the second quarter was largely a reduction in consumer gripes about billing and rates. Consumer complaints about carrier marketing and advertising, early termination of contracts, electrical interference, service quality and coverage, and tower and licensing issues have all grown. Wireless billing and rate complaints dropped from 4,006 in the first quarter to 3,320 in the second quarter. Overall complaints fell from 7,330 in the first quarter to 6,783 in the second quarter.
