Warning: Virgin Atlantic cannot redeem on KLM/AF

I recently took advantage of the AMEX -> Virgin Atlantic transfer bonus of 30% to book some very decently priced reward tickets operated by KLM from AMS to Africa.

During the booking, I was given error after error of a constant spinning wheel or the "this flight is no longer available." Unfortunately, I just spent the last few hours talking to both Amex and Virgin Atlantic who informed me that Virgin has had an issue "for the last month" in redeeming any flighty on KLM/AF. They said this is a known issue and that they have no idea when it will be resolved but said it will be "at least into July".

As the flight I am looking at is happening in July, it is incredibly frustrating. They said on occasion they have heard of a customer or two who has been able to get booked through, but they have no clue how.

Is anyone else having this? Given how Virgin Atlantic points are using the best way to fly KLM/AF in business class I haven't seen anyone post about this on here. Be warned! And share if anyone has had success.

EDIT as of 6/6 2pm ET: SUCCESS! It took 5 calls and 2 escalations to get to someone that would actually call KLM on the phone and confirm the availability to book the flight. Lindsay at VS support is my hero. She spent over an hour with me on 2 phone calls to make this work. Appreciative of all the comments here.
