Worst tool brand aftersales DeWalt sucks

I bought a brand new DeWalt cordless drill from builders. Almost R5000. 3weeks, chuck breaks, take it to a recomended place, Toolnet. 9weeks later get the drill back fitted with Metabo chuck. Had to pay R516 for the chuck because its Metabo. 1week of use, the Hammer action does not work at all.. Contacted DeWalt from floor to Sales Manager, no one comes back with answers, no one wants to help! Why buy brand names if I dont have any aftersales service?? Might aswell buy china brand and just chuck it out when it breaks!! Never again will I buy, recomend or support DeWalt.
