My product EAN has been changed, why won’t Allegro change it back for me?

[Sinocare_Direct]

Hello, I would like to ask Big Seller:
I sent my product to Allegro warehouse, and my product EAN code for example is 1234, but during the editing process, Allegro system kept asking me to link other products, otherwise it would show "no connection" status, and when I successfully linked, my EAN code was no longer 1234, but other codes. This means that I can no longer sell this product to other customers, because once someone orders it, the warehouse cannot ship it because my EAN code has been changed.
So, can anyone tell me what to do?
It is worth mentioning that I sent many emails to Allegro customer service, and they usually only replied to me that they received the case, but there was no reply afterwards.

Another question: In a batch of goods I sent to the official warehouse, one of the SKUs had a quantity of 100. The warehouse showed that 100 pieces were received, but there were only 92 pieces available for sale. I asked them where the other 8 pieces went:
They replied:
‘’Thank you for your patience.

Initially, the receipt of 100 pieces was marked, but an update was made when splitting into 8 pieces, so 92 were delivered and accepted.

The quantity is correct now.‘’

Can anyone tell me what his reply means?

92=89+3（sold is 3, not 2）

@Sinocare_Direct Please wait for an email response from your advisors. The response time depends on the number of applications we receive.

As for the second question, can you tell me the ticket number in which you received this answer?

Case no.：43133838

The case number for the first question is: 43189933
Can you also help me check it?
Customer service has never responded to me, and it has been 6 days.

@Sinocare_Direct We have received your message, but there are a lot of reports. I'm sorry you've been waiting so long and I'm asking for a little more patience.

Nie piszący po Polsku użytkownik odkrył Amerykę zderzając się z rzeczywistością allegro

@Sinocare_Direct gdybyś żył w Polsce to byś się bareizmom nie dziwił

Thank you for your reply. I think you expressed something humorously, but I didn't understand. Thank you for participating in our topic anyway.@RED

@ko_alka Thank you for replying me
Today I received another reply from the customer service, who told me: I was informed by the warehouse when we received the goods that there were 100 pieces in the delivery note. However, in the end we accepted 92 pieces and you can check this correct quantity in the Stock tab.

This reply did not solve the problem at all, 100 pieces, 92 pieces. He did not tell anyone where the other 8 pieces went, nor would he help you check, nor give you any solutions or suggestions.

I am very distressed.
