Awful working experience

I started working at Studio88 November last year and got '' let go'' in January this year as the manager there put it via whatsApp because she wanted her friends to stay in the same store as her but they had stores they were working in and when we reported the matter the big boss did nothing and she came up with an excuse that we failed the test, mind you we wrote the test and you are only hired when you pass, and my question was how come we were hired in the first place if we failed coz it didn't make sense. Then few weeks back the HR lady called me regarding a position in another store then when i asked if i can wear my uniform she asked if i worked for the company before then i said yes and told of how i was fired in the store i was in she said she will get back to me, i whatsAppes her, texted her and never got a reply back... So basically my experience with Studio88 has been awful. Now i am unemployed because of people who favor friendship over business
