TymeBank Debit Hold Problem

I have been calling TymeBank for the past two days now asking them to unlock my account as it is on debit hold. The consultants have been telling me that the matter will be resolved within 24 hours. Yesterday I went to the mall and I couldn't buy anything because the card transactions failed due to debit hold. Tymebank does not get back to you if your airtime has been exhausted while helping you. Can you please assist as I don't even have airtime to call them anymore.
