Another upgrade, another issue

Time for another upgrade and again I'm having issues. I did an upgrade almost 3 weeks ago. I was told there was no stock due to the unrest and stock would be received on the 23rd of July ( 1 week after the upgrade was done) On the 23rd I called an the agent assured me that stock of 3000+ black and 1000+ blue Samsung A12s will be received on the 23rd. I then called on Saturday, the 1st agent told me there was no stock and while I was speaking just transferred me to a different agent, The second agent was just as shocked as me when he original call dropped and she then ended up speaking to me. She was very helpful and told me that stock was received and confirmed that numbers as above. She told me that I should receive my order by the 30th. I called again on Tuesday and was told that the stock is there and it will be escalated to the warehouse to try and get the order out ASAP. Yesterday I used the chat service and was told that these phones are not in stock as yet and when I said that the previous agent confirmed stocked was received and that it will be delivered this week then the online chat agent said If that's what I was told then it will happen even after she told me there was no stock. Today I called and explain all the above and was then told there is no stock, the agent check a list and found that my order was not on that list and then told me that they will only receive stock next week Friday. I asked to speak to manager and was told that she is working from home but she will send an email for them to contact me and I have yet received a call. How much longer will I have to wait to receive my order??? Can someone give me accurate information!!! This is not the 1st time I'm having an issue regarding an upgrade order. I need urgent assistance so I can receive my order ASAP.
