Probably my final update on this one. 13 hours after I sent a refund address to the Telegram wallet support bot, they finally processed the refund and sent the bitcoin (10k sats) to the address I provided. They used part of the refund amount to pay for on chain transaction fees, which I had no problem with (fee was high, 30sat/vB, totaling almost 6.7k sats). What I had a problem with was almost 600 sats were sent back to the original address where I had originally sent 10k sats to the Telegram wallet. That means I only got about 2.7k sats back into my external wallet. Yet, in the confirmation message they sent out in the Telegram wallet, they never mentioned withholding / sending back almost 600 sats into the original telegram wallet deposit address.

Once again, I wrote to their wallet support bot asking about the reason for withholding almost 600 sats. I asked about the discrepancy between their refund confirmation message and the actual refund amount as indicated by the on chain transaction.

Also, I tried clicking deposit in the wallet again and got the following message:

Seems like they not only flagged my transaction, but also flagged my account and won't let me deposit anymore bitcoin. Of course, I also asked about why I wasn't able to deposit anymore.

I got the following response almost 5hrs ago and have not receive any update since:

Everything about this wallet just seem off for me. As if no lightning support, using on chain only isn't bad enough, they had to kick it up a notch to do legacy address only with no segwit support.

The act of sending almost 600 sats back to themselves and not telling me about it seems strange. Was that a fee for processing the refund? If so, why did they not mention it up front, but instead, tell me that they refunded a larger amount than the actual amount? Was it a dust amount that they keep for chain analysis? Or was it just a mistake, a human error?

Then disabling my wallet from further deposits is just a d*ck move. Censorship at its finest. If you send anonymous coins into this wallet, expect your whole wallet to get banned.

All in all, I rather Telegram not add bitcoin support to their wallet. By adding bitcoin support the way they did seem like they were trying to give a bad name for bitcoin. Imagine a newcomer trying to use bitcoin for the first time; and Telegram's wallet was their first experience with bitcoin. The new comer would think that what other shitcoiners had been telling them were all true; that bitcoin is slow, cumbersome, and expensive to use. Where, in fact, it is only Telegram's bitcoin wallet that is slow, cumbersome, and expensive to use.

So my transaction got 2 confirmations just now, and I got the following message from the wallet bot

As of now, my wallet shows the following balance, with the 10k sats showing on hold. I guess it’s going through chain analysis as we speak lol

Hey thanks for helping out.

So yea, after 10 hours of funds being “on hold”, I reached out to wallet support. This is what I got from them.

Pretty much the same response as what OP got. So coinjoined sats are high risk and not ok to be sent to Telegram bitcoin wallet, even if it’s only a small amount. Not to mention using legacy addresses and fully custodial. This wallet’s so called bitcoin support is simply horrible.
