Unprofessional service from SSS Cellular

Received a call at 10AM from a technician on the 2nd of march from sss cellular to come out to have a look at my samsung mirror fridge. Made arrangements for someone to meet with the technician at my property only to find out the technician never pitched the whole day. The technician never called to reschedule or anything of the sort. On the 3rd of march, i have been trying to get hold of SSS cellular to find out what is the issue and when will the technician come out. No one has been answering any phones or anything. This is really ****py and hopless service from an authorised service center. Two days of arrangements had to be cancelled to accommodate the technician and not one of the days have i recived any info as to what is happening. I have spent 48 minutes on a cellular line with the call centre only to find out the exactly same thing i knew before call the center. "The service center is not answering the calls"
