Dispute

Not impressed with their services. They have all the time in the world to to send threatening mails but have none to respond or check they mails. They been claiming i don't pay my account, i have sent my POPs more than once but noone has the audacity to contact me back, my credit score has been affected because of their incompetence. I've sent numerous emails to *** *** along with proof of payments. I've used the same process to pay for 3months but the only recognize 1 month's payment, why can't they they use the same processes to trace other payments.
