Bad customer service

I am beyond frustrated and annoyed with GETBUCKS and nimble. You guys have provided me with the worst service and could not resolve one issue in two months... I have made a payment a month ago and to date the payment hasn't been allocated... I i have spoken to numerous consultants and even a supposed manager by the name of salieg kok or promises resolve issues but hasn't done anything in three weeks... My credit record is being affected badly as this account remains in arrears due to payments not being allocated and I wanted this issue to be sorted in the month of August......
