Pathetic Service from Siya@Russells&JDG

I ordered a washing machine online on 26November 2019, it stated that delivery is 3-10days. On 28 November 2019 someone from russells call to say the delivery will take 20 work days. I asked them to rather cancel and refund me so I can go order it from another retailer before black Friday specials period end. On 29November somebody called to say they arranged with a sister company to deliver the machine over the weekend. We ended up arranging delivery for 3Dec 2019. On 3 Dec someone named Siya called from *** to let me know the machine will be delivered on 11Dec. When I said I was concerned at this changing stories coming from a big company like Russells and JDG and if the machine doesn't arrive on 3Dec as arranged they must cancel&refund me, he became so rude, even raised his voice, talked over me and was just condescending. When I asked for his surname he sarcastically told me he doesn't have a surname. This is disgusting from Russells. If that washing machine doesn't arrive today, I want the order cancelled.
