Made to run around for damaged cushions

Im p***** off by this store now I mean on Monday I went there and I was buying stuff and I told the lady at the till that I bought cushions about a month ago and the threads are coming out badly and I lost the slip and they are in my bar couch which we hardly use so the lady spoke on the phone with the manager and I showed them the pic and Tuesday I went there and guess what it was stock taking and I told that lady I was coming the next day why didn't she tell me its stock taking from 3pm, now I go to the store and I get an assistant manager (Lucrica) who doesn't want to exchange the cushions and I asked for the manager and she says the manager doesn't want to be disturbed they asked them not to call them, and I must leave the cushions and they will call me tomorrow do I have petrol to go there everyday like really? I mean even asked my colleagues here at work and they were shocked of the response I got as one said she bought a jacket at Foschini in march and after june she returned it because the buttons are coming out and they didn't have a problem, this store need to take their staff on training and the manager also needs training im the customer cant she talk to her clients
