Rude Customer Service Agent

My Vuma router was installed 3 days ago, I received an sms saying the wifi will be active within 24 hours, it's been 3 days and it's not working. I contacted the service provider SADV and they kept telling me my router is active. I then took initiative to contact Vumatel directly only to be assisted by a very rude lady by the name of Debrah/Deborah. She told me on the phone that I am abusing her when I told her I can't find my order number and that isn't there another way to link my info. She kept babbling about how customers are unreasonable and all that nonsense. I'm not happy with the service at all, I'm frustrated already that my wifi is not working only for Vumatel to be rude to me
