Pathetic Service

I purchased a Samsung s7 edge in Feb, on Tuesday this phone went dead and refused to charge, it was then booked in at "wefix" fourways crossing as per the samsung agent. I was informed by the technician that the screen and battery needed to be replaced and the phone would be ready for collection by Friday. I got an sms this morning notifying me that the parts had arrived but no call since. I then called in at 14:30 and spoke to the same tech who informed me that the phone is repaired but i cannot have it as samsung system is offline and i can only take my device on Monday. This is pathetic service as i wasnt even given a loan phone or a call, and it has nothing to do with me that the sysem is offline, why must i be affected or penalised due to this.
