Im cry 23/8/12

at first I didn’t get a single 4* card 160 pulls in a row, then 3 cards of 4* rarity fell out in one ten, but now I again don’t get anything in the amount of 120 pulls, I’m already roaring from such luck in the gacha, is it really difficult to make guarantors ?? ? update: I pull 30 more times and still didn’t get 4 * (in total, nothing falls for 150 pulls)
