When I looked over transaction details, somehow this address 0x4cb7d3b010c7eb7d7150266d9475fc175f73f6d0 has changed to this address 0x4cB7d3b010c7EB7D7150266D9475fc175f73f6d0 .
The only difference between the two addresses is that the first one has all letters in lower case.
Ethereum addresses are not case sensitive. If that is really the only difference between the addresses, you didn't do anything wrong. The exchange provided you the address in lower case, but after the transaction got registered in the blockchain it shows the address with case sensitivity that is used for optional checksum.
If your ETH didn't appear in your tradeqwik.com balances yet, contact their support with your transaction ID, it is probably an exchange problem.
How can we trust this transaction happened or not? Can you please give us full details and transaction links. Because this address looks like someone is edited. Once you provide full details, then you may get help from people. They will give you a solution how to get back your coins.
