Horrible Service

Purchased a brand new cell phone from Game store, Tygervalley on the 05th of May 2018. on sunday, the 05th of August 2018, phone just went dead. not working any longer. went in to store immediately after phone went dead. was sent to customer service. terrible, terrible service. advised the assistants and store manager that i dnt want the phone as it is a 3month old phone that just went dead. i was told that the phone has to be sent in to their supplier to ascertain what's wrong with the phone. I am so furios as I DONT WANT THE PHONE BACK. I was given a loan phone had i not insisted that we are not leaving the store without a phone. was told guarantee only 7 days. really??? on cell phone??? 3 month old brand new phone just dying, dead as can be and i can't get my money back?? And then they send you to Customer Service but clearly they dont have any idea what the meaning of customer service is
