Customer service is so rude

We don't say anything about service because there is none. We went for exchina force yesterday and once again when we got home they didn't give us the discount. This morning I had to go back get my discount, but the lady at customer service was so unkind you would think She did me a favour as always we also didn't get my 10 percent discount . I pay R99 a month for it....why i dont know yet The other time I asked about it they say I must just activate my discount on my app. Now she said I must also tell them about my discount. Are they just lazy, slow or unwilling to work. There are so many people without work that would do better. Please train you people in customer service
