Bad attitude

I phoned in to query a promo bundle of 500 meg that went lost at Vodacom when my contracts were transfered from nashua mobile to vodacom. The lady who answered the call was exceptionally arrogant and treated me as I was a supplier to vodacom in stead of a paying customer. She told me that I do not have the 250 meg anymore. I asked why and then she asked me if I upgraded recently. I said no you should have it on your records. She asked me again what I phoned about and then I repeated myself. She got irritated with me and threw her headset down and ignored me when I tried my bnest to explain to her the situation. I must say that the service i use to get from nashua mobile call centre was not good. But the service that i get from the 111 call centre is the worst i have ever experianced in my career as a call centre executive. Please can someone verify
