Good...but please make it better

Ive have been studying Chinese for a while now. I am currently living in China. I bought the app add on for the flash card trainer. However there are many words that it mispronounces. Example：呢 (pinyin:nē) the app pronounces it sounding like knee; then 没关系 (pinyin: méi gūan xì) the app pronounces the 系(xì) like with a sound like the word "eye" (s/eye)....please fix or refund me my money.
