Insufficient customer care assistance

I bought J4Y 60 minutes for 2 days(10am to 1pm) and J4Y 60 minutes every day for 3 days that were both activated the same day,but I have noticed that I am benefiting from both because after a 60 minutes is exhausted then that would be the end of that day,while hoping that once the first 60 minutes(10am to 1 pm) is consumed up then the other kicks in.I tried calling customer care without reach,except a voice prompt that is experiencing a high volume of calls.
