Hello, here is around 6 days, I bought some bitcoin, after they sent them, I did not receive anything because the transactions remain unconfirmed for 1 week.
In addition, only one of the two appears in the blockchain, one of the two seems to be in another blockchain (mempool)
The mempool is not another blockchain.
Mempool is where
unconfirmed transactions wait to get included in a block. Until a transaction is included in a block, it is not in the blockchain.
When a transaction is included in a block it is considered confirmed.
I checked your transactions, and you are even overpaying fees according to blockstream

I used this tool from blockchair.com to broadcast your transaction again.
https://blockchair.com/broadcast But blockchair.com refuses to broadcast it. It shows a message that the transaction is being broadcasted, however I can't see it in its blockexplorer.
Can you tell us a bit more about this transaction?
Did you try to use RBF (Replace by fee) or something like that?? I don't know why blockchair would refuse to broadcast it.
Edit: As pointed out by odolvlobo, the coins you are trying to send are still unconfirmed. Only when those coins which you received are confirmed you will be able to send.
I bought the bitcoins on coingate which is working with an exchange, what should I do exactly? Because at my level I have one of the two transactions in my unconfirmed wallet, and one not even happened in it.
I contacted them, and they told me the network was congested, except the charges are overpaid, and I checked, RBF is not possible
