Vodafone & Tigo – I can't "Twi Kɔ” cos "Mi suro"

My hopes of winning over 10,000 GHC in cash are over. 
My crime? 
I don’t buy scratch cards.
Am I the only person feeling ripped off?
As a user of both Tigo and Vodafone services I feel their current scratch and win promotion doesn’t favor me. I believe there are others like me and thus the reason for my rant this morning.
Vodafone and Tigo have both launched a scratch and win promotion which is ongoing. Vodafone’s “Yee Twi Kɔ”and Tigo’s “Wo suro aaa wondi” are set up to get their customers buying airtime in the hope of winning a prize.
Unfortunately my chances at winning any of the attractive prizes, which often are in the form cash, is non existent because I do not purchase scratch cards to attain airtime. Either postpaid handles the airtime or it is transferred via mobile money or Express Pay.
Considering that the digital methods of accessing airtime exist and save the networks money, I find it difficult to understand why users who purchase airtime outside of scratch cards can’t participate in the promotion.
I feel that in a Ghana where a cashless society is being pushed by the banks and even the networks, that it is important to to level the playing field rather than make one method of accessing airtime superior.
The reward for scratching a card can win you over 10,000 GHC. Meanwhile purchasing airtime digitally just offers you convenience. If you ask me it seems as if both companies prefer customers buying scratch cards than purchasing airtime digitally.
I just think that both Tigo and Vodafone should come up with a scheme to allow their customers who purchase airtime digitally to benefit from the ongoing scratch and win promotion.
Post paid customers can be given tokens or sent at random, a digital ticket that puts them into a raffle to win one of the prizes. This can come with conditions such as early payment of bills. 
For those who purchase digitally, each time a purchase is made a digital ticket can be sent to the user to enter a raffle to stand the the chance of winning.
What do you think about my suggestion?
Stay winning and remember to always keep it One HONDRED!
