Slottica Casino - BTC deposit not credited in account and 3 weeks not refunded yet

I created an account with Slottica on June 26th 2021 after finding their good rating on Askgamblers.

In their cashier I found the following information about the payment methods they offer: the popular e-wallets that I use – Ecopayz and Skrill were not listed. Visa card was temporary unavailable because of technical problems. Master card was available but with 5% fee.

In this situation, the most appropriate way to deposit for me was via Bitcoin. So, on July 4th I made a €1,200 deposit request in the cashier via Bitcoin. I got instructions to transfer the amount of 0.04232264 btc to a specific address. I did transfer it and after the confirmation by the network I received a message by Slottica’s cashier saying that the transaction needed to be verified manually. In fact my account was not credited with those €1,200 but someone needed to check it manually that I had really transferred 0.04232264 btc. It was Sunday morning, so, I patiently waited until Monday evening to ask Slottica’s support what was happening with my deposit and I gave them the btc address where they could see it. They replied:

05. 07.
‘We kindly ask you to wait for it, We are so sorry but that can't speed up the process, you have no reason to worry, you won't lose your funds in our casino.’

I waited two more days and asked them again. The replied:

07. 07.
‘Our payment team will refund the deposit to you. Please, specify your bitcoin address.’

I gave them the btc address where they should return the deposit and their reply was:

07. 07.
‘Our payment will refund your deposit shortly, we kindly ask you to wait.’

Subsequently, I wrote to their support team many times. They wanted the btc address two more times and each time they assured me that I would receive the amount really soon. In the last emails we exchanged, they were determined that they had already sent the amount:

12. 07.
‘The funds have been sent. Unfortunately we can't give you any more information. Please wait for it to arrive in your wallet.’

16. 07.
‘We kindly ask you to wait for it, as funds are sent from our side.’

21. 07.
‘Our payment department kindly ask you to wait, we understand that you have been waiting for a long time, but, unfortunately, we only ask you to wait more, your funds will be on your balance as soon as possible.’

Today is July 30th already and I have not received the amount of 0.04232264 btc that I had sent as a deposit to Slottica on July 4th , yet. According to my Gmail counter, I and Slottica have exchanged 33 (thirty three) emails already with topic ‘Bitcoin Deposit’. As my dialog with Slottica got monotonous and unproductive, I decided to share my case here and I am asking for your cooperation to get my deposit back.
