Very Disappointed Customer

I am receiving the worst customer services from you. let alone communication from Barko Financial Services , I was harassed woken up in the morning for this account to pay it, and now I have paid the account in full no one is willing to close the account, when I call more than 8 times to get assistance no one knows anything and I was even advised to go to the branch, is this this the services am I supposed to get from you for taking up a loan, to my shock even the lady I was dealing with is no longer coming back to me let alone to reach out, settlement latter has been provided to me but no one is willing to listen to me, they even hang up on me and trust me I have not started with making noise, I had an account before with Barko and it was closed easy I never went through this, from Written of to Arreas, I am not done I am still going to escalate this, I have given more than 7 days to fix the error and now this is happening to me,
