On the 19th of October ZESA announced that the minimum token purchasable through EcoCash, OneMoney and other platforms was being raised from $10 to $20. 9 days later, on the 28th they announced that the previously announced minimum purchase would no longer be in use. The new minimum token purchase is now $50.
Considering that the moves come in such quick succession, one would expect that ZESA should have just made the jump from $10 to $50 if they knew that this was their intended destination. It seems as though this recent change might be why ZESA’s prepaid vending system was down countrywide yesterday.
