They are correct. If you can show the 65k/month transfers for 12 months solid, ie the second year, you may be able to convert to that method. As always depends on you immigration office and the mood of the person you are dealing with at that moment. Either way make sure to keep the necessary funds in your account until the conversion is complete. If you drop below the minimums they can and have said your visa was invalid so you have yo start over.

if they didn't respond after you uploaded the requested documents they m8ght have missed them. From their standpoint they might have assumed you never responded and so were no longer interested. But just a guess. You could always try re-applying.
