I need access to my internet banking App!!!!!!!!!

Capitec bank is the most *********** bank in South Africa!!!! I am currently outside the country and need help with internet banking. I sent an email +week ago there is no response. I have called all their numbers , some time last week some agent told me the IT department would call me within 48 hours until now nobody has called , just poor reception and just being inconsiderate! I have asked for an alternative number to call they keep telling me to call the same number that has terrible reception.
