Not willing to honour guarantee - finding excuses charge for repair

Job no. 27302 -. Chest freezer handle broke withing 3 months of buying the freezer. technician tells me that he needs to charge me for the parts. Call centre speak to tech and the new excuse is because it is used for business, the warranty falls away.

I was never advised of this. In fact the freezer was sold to me and delivered to my business without any warning that the warranty will fall away.

Please honour your guarantee, or as per the consumer protection act, i am entitled to a full refund or repair for the freezer, due to the fact that this inferior quality product being supp****, it did not even last 6 months.

Please rectify this a.s.a.p.
