Sounds confusing but simple to understand. 3 months free is separate so you get that by migrating to them. The R5k is for everything you claim after that like the R999 Vumatel Activation. The R999 for the router and then what ever amount you claim for cancellation. Since the R5k can not be carried over I would suggest taking the router because it's free and included in the R5k. Then claiming the cancellation fee by sending email to
[email protected] and then 2 days they credit your account with it.
The only issue is you would need to pay home connect the R2288 for the cancellation if you want it right now or just wait cancellation period but doesn't make sense because you would still need to pay home connect.
You won't be able to claim the R2288 if you decide to wait another 30 before the line is released as far as I know it must be as a cancellation/penalty fee for cancelling now.
