Teleperformance

I work for healthnet account. My co workers have been talking about me and harrassimg me about the calls I take. I try to assist everyone on my calls but they are not taking any calls which leave them to loud talk and make jokes while i'm on the phone. I'm constantly telly them and the supervisor I can't hear provider on the line. Plus they are are talking about my smell. I don't have one and I take baths.. It's getting to the point where i'm crying on my calls because they talk about me like a dog and I don't bother no one. I tried talking to my supervisor about it but they just say ok and do they same thing as her co workers.. I need this job.. This was my dream job but since they ppl make feel like I shouldnt come to work.. What should I do
