Pathetic Service

Booked s7 edge in at the repair centre century city 18/01/2018 and was advised repairs will take 4-5 working days. Called last week no answer . I did online chat with Moipone with ref ********** 379 who advised me he can't track anything on the system and will get back to me and to date no one called!!I visited the branch on Saturday 26/01/2018 only to be informed they waiting on parts and they only receive parts once a week and that's on Mondays. Called again yesterday 30/01/2018 finally I spoke to Dorelle who advised me still waiting on parts. 8 working days and still no positive feedback. How is it possible that no parts were received for the phone? The service is really pathetic!!!
