70h+ sent me a coupon code yesterday but its not working.

I was going to order but now I'm kinda upset. Will update if they ever get back to me..I once got a coupon code from 7ohblack and the next day it didnt work as well then they told me it was expired. so I never ordered from them. It was upsetting. I actually liked 7oh+ products but I'm not going to play this game of false advertisement
