Screen repair no stock waiting for Korea to send

I took my phone to the service department ref *** because my screen was cracked. They told me it will take 3 working days to repair. Today is the 8th working day and it is still not repaired. Today I was told they don't have any parts and they are waiting for a shipment from Korea and they don't know how long it will take. I asked if they will give me a loan phone and then I was told to come and fetch my broken phone and us it till they get parts. If you phone head office in Bryanston they take your name and number and say they will phone you back in 48 hours. This is the worst service ever. You pay a lot for the phone and Samsung cant even fix it. The Manager in Brayston don't even want to talk to customers, I waited 17min on the line for somebody to tell me the manager don't want to take my call. Lots off idiots working for Samsung
