Bershka Mexico Keeps Cancelling My Orders Without Clear Explanation

I am writing to file a complaint about the constant cancellation of my online orders with Bershka Mexico, without any clear explanation. I have tried to place around ten different orders over time, using different customer accounts, different mobile phones and several debit and credit cards from different banks, but every single purchase has ended up being cancelled. The most recent attempt was on October 27, when I placed two large orders for my business, for a total of 42 items, divided into one order for 20 pieces and another for 22 pieces. Both orders were first confirmed and later cancelled. As an example, two of the affected orders are 40316177781 and 40315947825, which appear in the system as cancelled, as shown in the attached screenshot. I have already contacted both Bershka customer service and my bank. Each side shifts the responsibility to the other and I have not received any concrete or useful explanation or solution. This situation is harming my business, because I have clients waiting for these items and I cannot fulfill their orders due to these repeated cancellations. I respectfully request that my case be investigated in depth, that I be informed of the real and specific reason why my orders are being cancelled and that I be clearly told what I need to do so that I can place orders again in your online store without them being rejected. My intention is to continue buying from Bershka on a recurring basis for my business, but I need a clear, definitive and workable solution so that this problem does not happen again.
