Poor customer service

Poor Customer service but they very quick to call you and do collections,now that you have paid they don’t want with settlement letters base on the agreement you have with them

I did an arrangement with them to pay for 6months and I even questioned can I pay extra to finish before the agreed time frame that said yes I called in to confirm that the arrangement is still the same .now that I have paid up I’m being told there’s still a balance and I hate the fact that’s we are being responded by automated messages or emails .so you guy better fixed this before I take it further I have proof of the agreement I even sent it on your email but you responding bull****
