unhappy Tyme bank customer

My son opened a Tyme bank account last year for his R350 SASSA grant money to be paid into this account, he has now received 2 pay dates (28/01 and 29/01) and the money is not appearing in his Tyme account. We went to the consultant at Pick n Pay in EERSTERUST to enquire and all he could say to us is to wait the funds will appear ,we tried to check on there USSD platform this morning but received a technical error message.It would highly be appreciated if somebody from Tyme bank can contact my son on *** with some assistance into this matter.
