TRYING TO VOID CONTRACT

i recently purchased a lawn mower and trimmer set from take a lot, i received the item and while using it i noticed that the item wasn't working well and started smoking. never the less i contacted take a lot and i was informed that they would pick up the item on the 27/12/2017, it is now the 2/1/2018 and they have not collected the item, i reported this to them on the 28/12/2017 and i will informed that there was an error and that the item will be picked up the same day which still didn't happen. i reported this again and the lady advised that the item will be picked up on the 29/12/2017. IS TAKE A LOT WAITING FOR MY 30 DAY RETURN POLICY TO BE OVER????? if so this is breach of contract!!!!!!!!!!
