Ridiculous service

On the 31st Aug 2022 I received an email advising order #*** has been cancelled. There was no communication or notes explaining the reason for the cancellation,as I signed on their website to check this immediately. I then sent an email to LayUp & MyRunway querieng this. MyRunway responded advising me to enquire with LayUp as they get instructions from them regarding payments. I sent a follow-up chat on LayUp's website until I decided to call their helpdesk @16h38. I spoke to Sandile who said he was referring it as it was unclear why my order was cancelled as my payments were up to date. He promised to give me feedback. Yesterday evening I received emails from LayUp advising a refund was processed to me following the cancellation of my order. This morning I received SMSes too advising of the refund. So today at 16h29 I called LayUp helpdesk again ,I spoke to Sandile who advised that his team advised that MyRunway cancelled the order as the ordered item was out of stock. I'm refusing to believe this as I've made orders like this before and I know the item gets reserved. I'm beyond frustrated by Sandile not coming back to me with feedback,I had to call in again. Even yesterday when I called in ,my call was cut twice and he never bothered to call me back as I had already provided him with my details. Not to mention there's been no response to the mail sent yesterday, to LayUp support including the chat sent.
