Poor customer service

After a several times trying to call food *****s market Fourways without being answered to check if I didn't leave a parcel I went to pickup at mall before going to their store, it was finally answered over the weekend by a lady who is very poor on customer service, after not being able to provide her with the til number, she kinda of insinuated that she cannot be able to assist me, which caught me by surprise, asking for her name, she reluctantly said it was Elsie, and asking for her surname and she refused to provide, and that left me asking myself questions about how is staff trained on customer care, I was really hoping that I will deal with someone who is professional and willing to assist, I was very disappointed 😞
