Frustrated Client

Very disgusted with such a big and recognised retail store, I bought a cellphone on the 20th May 2023 at PEP cell store in Galleria Mall KZN, as my other phone broke and needed a cellphone urgently for work purposes. The phone only worked for 2 days and it started requesting me to insert pin which I never created. After work Tuesday afternoon I went back to the shop and requested them to assist with unblocking my phone which they couldn't help me, they just advised me that they will have to book it in to go back to Vodacom and it will be back in 2 weeks, hell no, why did I even buy this phone in the first place. Ended up taking the cellphone myself to Vodacom in town on the 23rd May and they charged me R120 to clear my phone. Cellphone worked for the few days (5 days to be precise), this afternoon I am busy on my cell phone and I insert the pin, it tells me incorrect pin but I have been using the same pin for the last 5 days. This is truly unacceptable, they need to relook at the handsets they are selling us. I actually need a refund I can not survive with a phone like this, today it's working the next day it's showing that i'm using incorrect pin. I will never buy a handset at Pep store in the future, never ever.
