Where is my Phone - Horrible Customer Service

My Samsung Galaxy J1 was booked into repairs at Dion Wired Store, Samsung Technicial desk at Cresta Shopping Centre on the 22.05.2015. I was helped by a gentleman called Thabang. I was told my phone would be ready for collection in 5 days time. Come Friday, 29.05.2015, I phoned to enquire on status of phone I was told by manager of Dion that Samsung technicians are no more based at the store, there was no status on where my phone was, who to contact or any forwarding details. I was told to phone MM All Electronics, the mobile number provided in constantly on voicemail. I mean how does this happen? How do you NOT provide contact details or communicate with customers about change in your status? Horrible Customer Service at its Best. I want my phone. I paid money for it and it belongs to me. Someone needs to tell me where and when I can collect my phone today. This is JUST NOT PROFESSIONAL AT ALL.
