Incorrect Information

On Tuesday the 29th of March 2016 i phoned the Samsung ADH center to collect my Samsung S6 for a screen repair. in return they said the courier company will collect my device on Friday the 31st of March 2016. On said date i phoned again and i was told that the loan phone was booked out and the courier company will be there between 09:00 and 17:00 at 16:00 i phoned again just to make sure everything was in order. i was told then that no loan phone was booked out to me and the courier company will not be coming. that i was to phone back on Monday the 04th of April 2016 to arrange for delivery only on Tuesday if possible. i think this is highly unprofessional for a big company like Samsung. and makes me question their credibility, should i maybe make use of a different make in future if this is the way they run their services.
