Manor Hill Brewing Ben Little Brew Master Sold me a bad case of beer it tasted like onions Ellicott City Maryland

On the first Saturday of January 2017 I went to Manor Hill brewery and purchased 2 cases of beer one of them was fantastic . but the brand called Citra Splendor tasted funky from the start and notified them via personel message on face book.  the next  2 cans were all right but then recently the next  6 I have opened tasted like onions or a bad pizza sauce.  Ben Little via a different personel message on face bookj said he would look into it.  He is the head brew master for Manor Hill .  He never replied back .    I have asked them to send me  a $75 refund for the bad beer but have not recieved any reply concderning it.
