I know and appreciate it. Just want to have an idea how long?

Hello,

Recently I withdraw my Bitcoins from Bitstamp to kraken using my old address (2017). After 6 confirmations, I noticed that the bitcoin is not on my account. I had a conversation with the support team and told me that my bitcoins would be delayed due to changes of address and will be charged by a small fee which is okay with me.  I asked them at least a timeframe when will be updated and they told me that it can take months depending on the developer.

Is there any thing I could do to expedite the process and getting my bitcoins from my old address to newly generated address? I think it would be unfair if I will wait for months.
