Poor service experience with superbelist ever

Bad service ever ,I've been calling I don't know since when I made return of an item and they collected the item from me but I never received the exchange item I've logged complaints several times with out getting any help ,my son won't have Christmas shoe because of these selfish people .. Secondly they delivered small sizes of 2 shorts I also logged a refund these nonsenses never came to collect the items it's I've been home the whole week they keep postponing I will never ever buy from them neverrrr they are the worst the airtime I bought trying to get help is now more that the amount of the items sies I'm so dissapointed and I will post everywhere that people if they will buy from this company they are buying at their own risk poor service ever .I thought they were the good.
