Ryobi machines at builders express store in Middleburg

Extremely bad service. I bought a edge trimmer from them Ryobi 3000, used one time for less that 30 mins and it started leaking oil. Returned back then they said it has to go for repair, all within a time period of a month. Anyway I agreed theyvsaid it will take 21days time passed i I had 2 go to the store and follow up no calls from them. Got thr machine back and I asked what was the problem lady at information said she doesn't know no job stating what was fixed. Machine was used the next day within 10 mins of work same problem Took machine back with the next 2 days I collected over the weekend. I tired to be fair as possible by asking for a replacement as last time my wife went to check they said they didn't have stock but they now do. I was refused an exchange and they said it has to got back for repairs. I had to call the branch manager myself has she wasn't available in the store, she then said she will try to resolve the issue with the supply. I had to then call the customer care line as I was in store for more than 1 hour 30 mins with getting no help. I then had enough and sa id I am leaving this machine here I don't want a exchange I want a refund done via eft as I will not be coming back to this store or deliver with Builders in future. After this extremely bad service I experienced I will not recommend my friends and family to use this store.
