***** case being covered and now i am stuck

I bought a lounge suit on credit. When i wanted to claim insurance because I had no income for 4 months I suspected ***** on my account as i was not allowed to claim insurance because I was apparently receiving income from a spouse who passed away. I reported ths to head office and I was made a deal. I paid the amount they gave me to settle. A few m8nth later I was told to pay another small amount which I did. I am still battling to get thw account closed and I am threatened with legal sms every day. I went to the branch where I get a nasty attitude and being treated like ****. I even contacted the regional manager who fetched the last payment from my house. Even he won't sort this out. My messages are being ignored. I was told by a staff member from another branch that I need to get this sorted otherwise I will be listed on ITC and never be taken off. This battle have been going on for longer than a year now. The couches I bought all have sagges and broke already. I will NEVER buy from Lewis again. No customer service and ***** being done on accounts and customers being treated like ****.
