The most horrible service ever

I took up a TV and a bed with Bradlows in Springs after a month i decided to go to the store to request the settlement letter for my account which i transferred immediately when i got to the store. I phoned JD financial services to verify if my payment was recieved and i was told i need to pay some fees after having settled my account. I asked how much i needed to pay as i wanted to transfer the amount i ddnt want any deductions on my account; they said they would forward everything a week went by with no response. I phoned again this other lady said the account was paid up and would send the paid up letter which she did. Now they sending me text msgs to tell me i need to have money in my account so they can deduct. I tried phoning them for the last 2 days and they just keep hanging the phone up. They answrr and drop. This is ridiculous and fustrating
