On demand unlimited incoming calls charges continue although I top up $20 and should get free
Please check my number < removed personal information >.
I topped up $20 for my number yesterday and was charged 0.59 for unlimited incoming call package so I unsubscribe it since I should get it for free for 20 days since I topped up $20. However today I was charged for incoming calls so I thought I unsubscribed it wrongly and resubscribe it however I got charged another 0.59cents.
Please assist since I should get free incoming calls for topping up $20.
