is there a time limit after which the offer is gone if not redeemed?

i'm going abroad tonight and wish to redeem it only when i'm back on wednesday.

Company paying for phoneline, gooding ✌️️

I'm using Digi new boardband currently. Initially realized that the WhatsApp call is not supported under this plan unless I pay another RM5 to subscribe the VOIP plan. So, after I subscribed the VOIP plan, my quota will looks like 6gb data, 10 Free streaming and 3gb VOIP.

Now after 2 days usage, I found out that all of my data usage including YouTube are deducted from VOIP 3GB quota instead of normal data. I felt something's not right there. The VOIP quota will be used up first before others. Meaning after 3gb VOIP data used up then I can't make WhatsApp call again even I still got plenty of normal data. Then how? Purchase another rm5 VOIP top up? Then all usage will be falled under it again! What a stupid method!

I'd called Digi help line and the officer told me exactly as what I'm thinking of and mentioned It's written at FAQ section. Yes, it's really written there, the VOIP quota ranged on the first priority there!!

So, any one facing same issue? Any solution?

Postpaid plans maybe more expensive, and got weekend 4G quota limitation. My house area has no 4G signal, no point to waste half of the quota with the plans.
