I am so Dissapointed in House and Houme

To whom it may concern, I opened an account with house and home Krugersdorp on the 07/2014, I bought carpets, tv, xbox, bed,tv stand and 2 x carpets on account. 3 months after I Phoned them telling them that the one carpet hair has fallen out and want an replacement, this was the 10/2014, they told me that the contract needed to be cancelled and must be done over when a new carpet is supp****, and after signing the new carpet, it happened 2 more times, one time with the bed and one with the other carpet. so by now I was Furious at house and home giving me unsatisfied products, 4 times this contract were done over, the first contract start at 07/2014 and ends 2017/02 but the last contracts end date move 3 months on from the 2014/10 - 2017/05. why would I pay 3 month more on this account, and now I want to settle my account with House and home, and they tell me that my amount owing is MUCH MORE then it actually is, after paying 3 months, the new contracts were set up I now need to pay 33 months on a contract that actually was 30 months, and the more I speak to Veronica, the more rude she gets, I really want to settle this amount but are not willing to be **********.
