Poor service

Hi my name is Matthews Sokopo i have a bradlows furniture account handed over to Nimble group, in numerous occasions i have contacted them requesting for a settlement discount of at least 50%, two of their consultants said they would get back to me for feedback, but never did, the third consultant i communicated with via email mentioned that they cqn only offer 20% but i asked if she could at least ask if it could be pushed further to which she ignored my email, giving me a take it or leave it type of attitude.. This people have a very bad service and they never even give feedback and to think that i even have a debit order with them but they still add interest regardless of the fact that they mentioned that thet were not gonna add interest if i set up a debit order..
