Skitto's Removal of 3 day mix deals

Im a normal guy, i dont use a lot of data as i work where they have free internet. But when im not at work, ie: on the bus or on the train, i need data, but i dont need a lot of it. Mostly just to check reddit, or facebook or just reading ebooks, so a 3 day 500mb deals is more than enough for me. The first time i got skitto, they had a 500mb deal for 12 tk. It was the best data deal i'd ever seen and i bought it every week at least once. But one day it changed to 18, this made me mad, but i kept buying it as grameenphone had a similar 500mb deal for 28tk.
It then changed to 21, and eventually 23tk. I kept buying it reassuring myself it was still cheaper, i dont know when but the price of 500mb went down to 21tk again which made me happy.
Just this morning, when i was gonna buy a 3 day mix 500mb deal, i couldnt find the 3 day mix, i thought, surely this is a mistake and i reinstalled skitto to check, but sure enough no 3 day mix.
This is the final straw, if i cant buy small amounts of data for a convenient period of time i will change to another network provider
