Dyson Sent Incorrect Invoice and Refused to Correct It After My Request

I purchased a vacuum cleaner for my company through the Dyson Turkey website and filled in all the required fields with my company details to ensure the invoice was issued correctly. However, the invoice was sent by email 10 days after my order and was incorrectly issued to me personally instead of to my company. I canceled the individual invoice, provided my company details again, and requested a corrected invoice. Despite this, Dyson claimed they could not cancel or reissue the invoice because the 7-day billing period had passed. How could I respond within 7 days when I only received the invoice after 10 days? To make matters worse, I received their response on Saturday, November 9, when Dyson support was unavailable over the weekend. By the time I reached them during the week, I was told there was no way to resolve this issue. I reopened a complaint, only to be told the same thing again, with no escalation or further support. This lack of professionalism and accountability is shocking. How can a company as prominent as Dyson struggle to manage its accounting process properly? I sincerely hope my complaint is resolved, but it feels like complaints are not a priority for this company. It is frustrating to purchase from a company that cannot even issue a correct invoice, let alone provide adequate support when errors occur.
