No after-sales service for damaged product

SA Garage Doors in Gauteng [URL Removed] replaced our garage door motor in December 2014, with the promise that it comes with a battery pack that will work for a few hours in the event of a power outage. The battery pack does not work.<br> I have made numerous attempts (phone call, sms, e-mails) to contact Quintin to come and look at it, but are blatantly ignored.<br> Terrible lack of service on a damaged product sold to us
