Similar experience here. Just a couple of form replies and then it was fixed, without any explanation, or addressing my specific "this keeps happening" concerns.
How long did it take from start to end?
Withdraw attempt was on 17th June, I opened a ticket on 18th June, was advised on 30th June that transaction had gone through.
In a subsequent ticket I mentioned: "As per my original ticket, I believe this is an ongoing problem. So I don't just want my transaction kick started in a week or two...how can we solve these issues once and for all?"
The reply said: "Thanks for your patience. We have refunded your transaction. Feel free to initiate the withdrawal again at your convenience."
I don't know if they've specifically been instructed to ignore/deflect queries about the ongoing CLAM problems or it's just the way support works. Twice they ignored my question about a proper fix.
