Bad service faulty unit

I bought a pressure machine which is a Bennett read on the 24th of June today is the 8th of August the machine stopped working I took it in to builders in Strubens Valley only to be met with attitude from both managers Evan Le roux and store manager Ghalieb Samaai who I request can I have a loan machine or an exchange unit in the mean time and they said NO it's not they fault and they can't help me with a loan machine or my money back bare in mind I use this machine once a day so I can feed my family but to them it was wait 21 days you will get feedback there nothing they can do but with attitude and smiles where I was made a stupid what kind of management is this to be honest. I called customer car spoke to Josh he requested the only person that will be able to help you in anyway would be the store manager who's not for to be one Ghalieb Samaai I really think this is pathetic it could have been handled in a better way staff behind the return counter even laffed at me while the manager spoke to me with attitude and made a mock of this.
