Having moved over multiple family members and myself, who all have Airtime Reward accounts, it's disappointing not to be able to use our credit towards our bills with SMARTY. Please sign SMARTY up.
@Sy Smarty provide a reasonable no-frills service at a good price and that is what attracts many people.
The cost of dealing with reward schemes would probably cause the price to rise and therefore defeat the USP.
In case anyone is following this, SMARTY became available to use with Airtime Rewards about a month ago. So, this one can be closed and completed.
