Bad attitude and customer service

Bad attitude from the telkom shop at Jabulan mall I went there on the 2020/10/09 and one of the staff told me that they were off line as I wanted to make a sim swap and I was told to bring only my I’d book or card for it to be done then on 2020/10/10 I went back to the shop and I was assisted by a lady by the name of Lucia Zulu and she told me that I have to give her my I’d number and proof of residence I told her that I was here yesterday and they did not tell me about the proof of residence they informed to bring only my I’d of which I did she then told she can’t help me, then told her that I do have proof of residence on my phone as I do receive all my mails via my email so I can be able to send it to them so I will need to buy data from her she then proceeded with the transaction and I bought a R40,00 rands data with R50,00 rands and she told me that she doesn’t have change I have to go and ask for change I told her that I can’t go as I am using crutches and can’t go around asking for change she then told me that I have to sit down I will be helped by another person she can’t help me I then asked her if she can’t ask for a change from her colleagues and she asked for a R50,00 rands change and they all said they don’t have, I asked her to ask for R10,00 rands and she will give it back to the person who borrowed her and she said the company policy does not allow her to do so and I should go and ask for it I then ask one of the salesman in the shop if he does have a R10,00 rands and he came and gave it to Lucia who was not willing to ask for it from him and finally she helped me I am really disappointed with her service she really don’t know how to treat a customer not happy at all
