Pathetic service from Incredible Connection Matlosana

I bought an iPhone 6s 2019 December, last year around October it started giving problems with the charging, I took it back to the store as it was still under warranty. That would be around November, I kept asking for feedback from the store and I was told it went for repair, around the January I'm told the phone has a quote for R5000 because the screen has physical damage. Went I took the phone to the store it was not cracked, the fault of the unit was that the charging port was not working. Now unit is out of warranty, they can't be involved cause is cracked and warranty has been void. When I took the phone to the store, I was never told about the warranty being voided
