Review Clicks rechargeable toothbrush dilemma.

I need to replace a brokenbrush head for a clicks rechargeable toothbrush . P. L. U. Code: ********. I have been to a couple of branches and staff have phoned other branches. They do not have spare “heads” - only the whole new package at R249.99. If this range has been discontinued, how can they continue to sell them if no replacement brushes are available???! Appreciate staff help- but frustrated. Help please.
