Replaced faulty tablet with another faulty tablet

Bought my son a tablet for his birthday in November 2017, at Ackermans in her m****. It stopped worked not even a week later. Took it back, waited longer then 2 months for them to return it to Ackermans after not being able to fix it they said they would send a new one. When I eventually got the call to pick it up. I took it home only to notice it was in worse condition. Had a dent on the front, volume buttons didn't work and you could see it was a secondhand device. Utterly terrible service. Never by an MTN product from Ackermans. Ever!!
