Thank you for your post and welcome to the forums.
Sorry to hear of the issues you and your daughter are faced with here. In terms of the issue with the microphone/sound, is it possible we could explore and expand on this. So what is the issue? Is it that the person can't hear you/daughter talking, or is it the other way round etc? As much detail as possible would be great 🙂
In terms of the WhatsApp, are the numbers saved in the phone as a contact? Also, can you expand on it advising the person doesn't have WhatsApp? I feel like this isn't a network provider issue but will be sure to double check.
Lastly, in which capacity is this showing that information regarding her allowances? On our app, through our website etc?
The issue with the data and minutes has resolved itself and must have been a temporary.
We have sorted the Whatsapp issue, basically the app was still installed on her new mobile number and she hadn't transferred it over when she had used the Pak code to keep her old number.
The issue with the sound during calls is still a problem though. It can be either way, in that when she receives it makes a call sometimes neither party can hear the other and they have to terminate the call and try again which sometimes works.
