Poor service and device

I'm not happy at all in such a way I wouldn't recommend pep cell to everybody and I don't think pep cell is doing business the legal way, I believe South African gov must review pep cell activities.

I bought a phone sumsang A 3 core on the 29/04/2021 on that first day it started rebooting, I returned it to pep store 4404 on the 03/05/2021 (4day period) and they give me a new phone in a hope it will be better, same problem happened I returned it the on 07/05/2021 (4day period) a new phone again was given same problem happened and I return it on the 10/04/2021 (3day period) and I claiming for a refund their manager she said "it going for repair I must wait for 6 weeks" or after their checked it, she refuse to sign a later of demand, I called their customer but still no refund was given I'm no longer interested. the 7 day period wasn't yet complete which is on their terms and condition, how she can send for repair a new faulty phone that been used for 3 days, business it not done properly any question contact me ***
