Terrible service

Handed my Samsung phone in at the Samsung store in Eastgate Shopping Centre on 2020-12-27 to find out if the screen was damaged due to water, paid R200-00 for this service and when I received call back this morning to advise that it was going to cost me R8 000-00 to fix, but they refuse to allow you to speak to the technician to find out what is wrong, store manager was very unhelpful and also refused to give a diagnostic report on the findings when sent to see what is wrong with the phone, it seems that no-one is actually willing to assist at all, very frustrating as it seems they are just want to make money out of their customers, very sad for a brand that I have had for many years.......
