Take allot unreliable

On Friday the 30 August 2019 my Hisense infinity E max was delivered. Exited to be able to carry on with my business. I'm self employed at home sales the in less than a day I found the device is faulty! The face recognition only works when it wants to. The hands free earphones during calls callers cant even here me.... With constant battle for reciption. I filled for a refund immediately that Saturday morning. Collected the faulty device. Yet noty money quick to take cash and do sales yet poor delivery of correcting what is done wrong. I phoned there so called customer care I cleared explained that I do sales I need to replace my cell phone as soon as possible as I work on it Fell on deaf ears even though I told the consultant I'll take another phone don't worry about it. I'm loosing sales commission.... Friday still no refund on the phone. Pathetic service with take alot if you people have time to play the rest of us dont..... I gave ur high promises the benefit of doubt yet you failed with it!
