Extremely poor online service from Game/Massdiscounters

On 28 April I placed an order for a washing machine (R5999) and a microwave (R949). Now, understandably, this was during the strict lockdown conditions so I had no expectancy to receive the order soon, but as soon as the restrictions were lifted. 13 May I received an SMS stating that I will receive a message from the courier regarding delivery. 19 May, while at work, the courier phoned to say they are at my residence. Thus, I had to quickly rush to get home to accept delivery. On the delivery form as well as the invoice is the full order (washing machine and microwave) and yet only the microwave was being delivered. I immediately tried to contact the online support with no one answering. I told the courier to please take the microwave back to the depot as I can not sign for both. As no one is answering the phones, I sent a friendly email informing on the situation and asking them to follow up with the courier. 27 May, just over a week later, I receive an email that "your order has been partially refunded". It is at this point that my emails are not friendly anymore. At no point was I contacted by them to discuss the matter and I have no idea why it is being refunded. Thus, I reflect my frustration in a response. On 30 May I get a response apologising for the inconvenience, but the item is out of stock. SO, how is it that I can order the item while it is "out of stock"? How is it that the courier is given an invoice for both items with only one being delivered? And again, at no point in time did they contact me to inform on stock unavailability. Now, more than a month after the order, I still don't have either of these items. The best part of it is, the washing machine is now going for and extra R500 more than when I originally placed the order, so now not only will I still be without these items, but I will have to pay more. Absolutely ******* service from GAME/Mass Discounters.
