Bad customer service and Premio faulty cellphone

On 28 March i bought a Premio at Attelyn Mall in Attridgeville Ackermans since July phone speaker doesnt work i must do loud speak to hear a person.Its presses itself when you charge.Most times you cant answer incoming call it germs on screen. I cant do anything about this phone. I went to complain several times where they told me i must call the supplier myself because its no longer they're problem. Also today 17 Oct i went to Gezina in ackermans to cancel my laybye as i have an account they cashier insulted me infront of customers due to the fact that i refused gift card because my laybe was not expired so i demand full refund. She stated unberabble words> Lebogang in Gezina time was9;15. How can you treat a customer like trash while they trained them for customer service.I buy my kids clothes at that store and every ackermans i went i was never treated like dirt except attridgeville and gezina. I will take my case further for what Lebogang did to me today even footage will prove that i was attacked by her. Thank you for a cashier who defended me may God continue to give you promotion. You have Best Customer service
