Bad call centre agents

Worst experience ever. They should be ashamed of the call centre people they use. Someone called me on from +27 87 ********** . We told them to call back later as we were at a funeral she called back multiple times and then when my girlfriend asked the caller to call back later she asked why she couldn't speak to me now. Then she had attitude and then eventually hung up. I hope unlimited get rid of people like that because those people drag your name through the mud. I never want to receive a call from them again!
