Huawei consultant cell c phoenix plaza

My mother took a huawei p10 lite contract from cell c phoenix plaza and she was rather concerned as to why has she not received a gift as there was a huawei stall at the front of the store and she questioned the huawei consultant as to why has she not received the gift as the consultant told her only if you take a contract of the huawei range then you would qualify..... So the consultant then questioned my mother what huawei it was and with attitude she humiliated my mother and said that she is the area manager and she is not giving out any gifts for p10 lite huawei..... I then stepped in and asked the consultant why is she making weird facial expressions with attitude as if she is doing my mother a favour and she said i should stay out of it as i did not purchase the phone and she is talking to my not to me... I then contacted the area manager who then tried to pacify my mum with a free gift to curb our anger of the huawei consultants bad attitude and she then instructed me to send me an email on her personal gmail account which is so unprofessional as i requested to have her work email as i do believe its the correct thing to do.... Uptil date i have a telephonic discussion where she did say action will be taken with the consultant and will revert back to me.... It is now one month and i have emailed the area manager and she has not responded.... I urge the community if a brand ambassador of a big brand such as huawei can be so arrogant and disrespectful and treat customers so caless it really makes you to think about twice about purchasing a huawei brand......
