The call centre is very rude

I have suffered irreparable damage due to the fact that I wanted stock pots from home choice. My life is a living hell I get fifty calls a day, I returned their posts last year and now receive calls my bill which I don't know where it comes from is going up. I don't have the pots and I paid home choice, is this not harassment ??? Today I spoke to Kevin Nkondisa who also did not understand and I asked to speak to the superior and he said they would call me back, only to at exactly 5:58 from a lady who cut me off when I was asking for her name. Please my account according to me I don't owe as I don't have anything from home choice and please only phone to resolve this issue, please I beg you before I make this ********. What is this really
