Pathetic service!!!!!!!

I was back on payments on my jet account however I went into a jet store and I spoke to one of the sales consultants at jet and they assisted me with telling me how much was owed, I then made full payment of what was owed and have paid extra. The sales assistant did say the outstanding account will be closed within a few days, it's now been three months and the account is still on my name and money hasn't been credited into my account, been emailing, calling nimble for assistance gas the jet account has been handed over to nimble and associates... Never again will I be opening up a jet account, it's too much of a hassle to cancel and nimble is a waste of time, they should just close they customer service lines gets cut and their consultants say they going to call me back and they don't
