I bought a logik blender which is currently on special for R255 on the 12 July 2015. I tried to use on the very same day and it switches on but does not blend the fruits. yesterday on the 14/07/2015 i took it back and they gave me another one and this morning i tried to make my breakfast smoothie and guess what ,,, it switches on but can only blend yoghurt and banana and not even smooth. i wanted to make a spinach and apple smoothie but it does not blend.<br> <br> I am so angry at the fact that I waited my petrol to go to your store and bought something that does not work AND returned it but it still does not work and now I must waist my petrol again to take it back.<br> <br> Game store should stop making these LOGIK BRAND COZ IT SUCK IN DOES NOT WORK IT DISGUST ME.<br> <br> i have sent an email to the head office and they call me and told me to return it to the store as if i just put water in my car and drive and all my fruit and veg's that i bought i must just throw them away as if money grows on trees<br> <br> To show that they don't even have confidence in they own brand when I asked them to put fruits or vegs to test it they asked me if I have brought my own and I said no and they
