Poor service

On the 1st of April I was able to upgrade. I chose a device on the website that indicates that there is stock. On the 6th April 2021 I phoned to follow up and found that Vodacom cancelled my order as the upgrades department never submitted the order. I then go though a telephone upgrade and get told there is no stock... That is false advertising as it does not indicate on the website that there is no stock. Now I must wait for the device and it is not my fault. All they say is sorry for the inconvenience. I am so tired of poor service and that after i have been trying to change my surname for the past 5 years with Vodacom. I do feel that i must be compensated for this as it was not my fault but Vodacom's. When is ask when the stock will come I get told to wait for an sms to say that the parcel has been dispatched. Really???????????
