My Everyday Locked for no valid reason!

They have locked my account without prior notice, i received salary on my Tymebank Everyday account yet i am unable to transact, i cant the bills because of this inconvenience, this morning i have been trying to get in touch with their call center agents but i stay on the line until my airtime depleted, if Tymebank doesn't want me as their valuable client anymore maybe i should move my salary elsewhere.
