Mondo Poor Service Delivery

I ordered from Mondo on 23 August 2019 two Samsung Galaxy A20 phones. Every time I enquire on when the package will be received they keep telling me the following week as they do not have stock. So Friday 20 September when I phoned them again - Note that I have made over 10 calls since my first order, they told me that they have finally received the stock and it should reach me this week. Yesterday I phoned again and the lady confirmed this and said I would receive my order by Friday on the latest.

I now phoned once again just to be informed by the lady that once again they ran OUT OF STOCK and will now have to wait a further 21 business days before delivery IF and WHEN the receive stock.

Yet they keep advertising this same phones on all social media platforms. How can you keep taking orders from people if you know you do not have stock???

My husbands birthday was on 13 September and this was supposed to be his gift. It has been more than a month since my order was placed and still when I phone the cannot even take the time to find out why it is taking so long and update me?

Please can you sort this out.
