Poor aftersales service

Selling a faulty FLXP12/2415 DC/DC Charger, Isolator

As advertised at Huntex, the unit comes pre programmed as per the towing vehicle and working with an app for monitoring purpose . Received the unit without any user manual, requested the manual and to date has not received it. Installed the unit in our caravan and plugged the caravan into my vehicle. Must say at that stage I still didn't receive the link to the phone app to be used.

One big bang and the caravan movers and fridges DC blows up. Input from vehicle 14.2 V output from the DC/DC unit 28.8V

Many whatsapp conversations with the sales agent to verify the unit settings and then per telephone conversation with Flexopower sales agent, he told me that his manager indicated that Flexopower are willing to refund the DC/DC charger unit but not repair the damage to the equipment caused by the faulty overcharging unit.

Very very bad service from an apparently big supplier.
