Hurricane Galaxy Cellphone

Just experienced the worst customer service ever. My cousin bought a phone on 23 December 2017 at Edgars Somerset Mall only to get home to find out wifi settings not connecting. He took phone back to store on the 24th of December - they checked it told him it should work now. He got home - same problem. He went back to store after the 2 holidays (chrismas and day of goodwill) - they checked again told him phone is working. He came back home still same problem and because it was Holiday he could only go back to store on 10 January to let them check it out. They took the phone in, booked it in for 6weeks for supplier to check out. He got phone back on 15 February 2018. Guess what, same ****** problem. Only for them to tell me now that phone must be booked in again for another 6 weeks or there is something wrong with the wifi router at home (mean while he cant connect to any other wifi then the one they have in store). They do not want to refund him nor do they want to give him a new phone. A phone which he bought with his hard earned money. They just keep on repeating the same story "sorry mam we can't refund him or give him a new phone". They are so quick to take your money but are not willing to walk the extra mile for a client. I'm disgusted to say the least.
