PAYMENT ARRANGEMENTS - RUDE STAFF!! THREATENING STAFF!!!

Opened an account with Lewis Stores the end of June/beginning of July as I needed furniture as I was forced to move out on my own after my relationship ended. I notified my sales consultant Athi at Lewis in Oxford on the twenty second of July that I would not be able to make full payment beginning August however I would catch up what was missed end of August as I am forced to move from my rental once again. I received a call from the Store and the lady that spoke to me was so rude. She went off on a tangent, talking about it's my first payment I HAVE TO PAY IN FULL or else they will come and take my furniture! I asked her for an email, stating this so I can try and make arrangements with my work. To DATE! I STILL have not received the email, to make matters worse when I asked her to put this on email - the fact that they would come and repossess my furniture even though I have tried to make arrangements to settle what is missed beginning August, she was rude and asked me "Why? Why should I?" ?? How is this an acceptable way for a company to treat a consumer? Life happens. At least I notified the Store and tried to make arrangements!! Instead I get phoned and threatened almost immediately!! What kind of company is this?
