Delivery does not match Order

I purchased a 220L fridge via online platform on 29 June 2020. On the 9th July a washing machine was delivered and then taken back and a 161L fridge delivered. I have sent 100's of emails and had calls with the call centre...but no support or response. No one cares to collect the wrong delivery or redeliver the correct item. I think they are wasting time and will eventually not even uplift the incorrect item and hope its forgotten. This is the worst experience i have ever had and will never use Massmart again.
