Unauthorized cancelation of order! Vodacom customer care is a joke!

I made a purchase on 13/11/2020 of 2 samsung soundbars and 2 galaxy watches. Payments were successful and reference numbers were obtained via the app stating that the purchases were completed. I received one sound bar successfully however no further sms or any communication was received via vodacom for the other remaining items. I've been trying to contact them since last week friday however I get told they will transfer my query to the loyalty department and get back to me, till date nothing has happened until yesterday the funds for the two watches were reversed back into my account(the one sound bar is still outstanding). Their terms and conditions stipulate that I would be contacted prior if the order cannot be fulfilled however nothing of that sort has occurred. I have tried contacting them telephonically to query this however they have now banned my number saying I am calling too much. What makes it further frustrating is that some of my colleagues who purchased the same items after me on the same day have received their items but I haven't. I've also tried contacting them via email and then Facebook messenger however they are of no help stating that I should reorder the items, they also tell me they have no idea who canceled my order. I have screenshots of all the above however when it is sent to them they say they are unable to view it . How can I reorder items if the sale has finished? Why advertise items saying my purchase is successful and then without even contacting me further cancel the order. I've been a loyal Vodacom customer for over 15 years and at this point I'm considering moving to another network.
