Damaged fabric Lounge Suite

I bought Richmond 6 Lounge Suite (Taurus Mud) on the 20 February 2015 in Rochester Polokwane(game Center). My salesperson was Mr Charles Manyape. Lounge suite 3 Seater started to peel off in July 2015,I went to report it and they came n collected it.They brought it back after 3 months and in July 2016 all 6 piece started to peel off again.I went into the shop again to complain and they told me that they have logged a query with head office and i must wait for reference number from their head office.I have been to their shops i don't know how many times since from last year and they always tell them about the new system that they are not able to operate.I have been to pillar to post regarding this issue since from last year.The last i went to the shop i requested that they give me their head office line so that i can talk to them directly but they refused. Yesterday on the 21/11/2017 i went again into the shop to ask what is happening and they told me that my claim has been declined because i put a query after my warranty have expired.I have been to Rochester furnisher i don't know how many times since from 2016 and now they are declining it. I have received such a bad service from rochester furnisher and i need assistance as to where i can go and complain.I paid my money in full but at the end of the day i'm stucked with peeling sofas that are not even 3 yrs old.When i bought them i was told it was a life time guarantee but now i have been taken from pillar to post.
