Rude and ****** agents

I had spoken to one of your managers who was very polite and nice but this morning of the call center agent call who was rude. She raises her voice, refuse to listen and at the end of the call I assume said something in her own language which was uncalled for and ******. If this is how you treat client under the bander of customer service, it very sad for you. Please may you get some to pull the call and get a manager to call me again.
