SLK Liquidation centre

GROOT SKELMS!!! Purchased a 2000w inverter, 150a/h battery and a 30 amp charger at SLK Liquidation about a month and a half ago. Battery started failing 5 min into load shedding. Took the battery in as i have a warranty only to find that the whole place is plastered with "warranty only valid if installed by qualified electrician and COC" who the hell will pay a electrician to write a COC for a sime instalation like that. A 4th grader can install this and this statement is unheard off in the retailing cheap products like these.. Making up their new rules as they are trieng to get out of the warrenties given for inferior products that they sell at basicly normal market value. Passop people they might have a thousand other rules that you will only see after the masses flock in to redeem thair warranties.
