I emailed her and she called me back to discuss options.
No new package was offered other than what was already posted in the thread, "best" was the 150 + 150 @ R399. So I don't think there will be BF specific retention deals.
My contract ends on the 11th so I asked about upgrading to some small package and then upgrading again on BF when those deals come out. She said I can do that but there will be a R150 charge to upgrade each time.
If I don't upgrade, the contract jumps to R1299/month (this is the 400 + 400 BF 2020 deal).
I'm going to "upgrade" to the 200GB @R399 month-month deal that's on the app instead of wasting R300 on fees.
From the Ts&Cs, that should have no upgrade fees for migrating to a VLC deal if something better pops up on BF. The data from the plan should also carry over to the new contract:
