Treated like trash

I went to Telkom Mobile the Glen to do an upgrade on my device, the contract is on my husbands name and when we queried if they have a 64G device we were told with an attitude they will check, made me feel as if I asked for drugs that I was not allowed to have, then we were asked for my husbands ID and he said he did have it but will go check in the car, as I waited I queried if the deal could be done and the ID brought in the next day (seeing that we are a client of Telkom's for over 9 years with more than just one line) and I was told no. When my husband returned he asked the same question and I stopped him say I already got a no. Simphiwe raised her voice at me in a store full of people and with a pathetic attitude saying I didn't, I was rather irritated at that point and in no uncertain terms told her that he service was putrid. She ignored me and when I reiterated it she said I heard you and will not respond. Please could the manager contact me as I will further escalate this. Its embarrassing to be associated with Telkom with this type of behaviour.
