Unpleasant customer service

My spouse and I have been struggling to get assistance form vodacom for while now. They have offers on their site, when you email for assistance, you are told those offers are no loner available. This is false advertising. To add to it. Today I finally got through to a representative Tarryn Hutton on the number ***, I think she is a contractor via Likeminds in KZN. Speaking to Tarryn was an extremely unpleasant, draining experience. She has absolutely no idea what telephone etiquette is and sounds as if she has no longing to be on this earth any longer let alone be in the customer service industry assisting customers. I have always been an avid Vodacom customer, but their staff really requires training and, especially the people who deal directly with clients. I suggest that the call being audited and used for training purposes.
