Feedback and refund

I bought a charger last month and it’s stopped working within 7 days,to it for exchange and I got another one and it did the same thing,a couple of days I had to drive back to their warehouse and return it,3days later I haven’t received feedback,so this is an I convinience because I have to wait for days for them to check the eligibility,and then process the refund of which that also takes a couple of days,as it is I’m still waiting for feedback,I’m without a charger and frustrated because ill have to wait forever to get my money back to go to a store to get a proper charger because I don’t trust them anymore,can someone give me feedback on the charger I returned on the 15th already,I drove to the Rivonia Depot to return it myself trying to speed up the process.
