Bias company

I am an existing cutomer for 3 yesrs now and I've been trying to add an additional line, the Xbox, onto my contract. Ive submitted online applications and no one has called me back. When i call in ,Mtn has been transferring me to different sales departments and sending me to their stores but no one can help .I'm Extremely dissatisfied with the service ,I have been receiving , why would you falsely advertise a device?? When my husband submits an application he is called immediately but unfortunately the contracts not on his name and i have to do an online application for the 10th time and get no response. Why is my husband called but not me even though you are aware of my complaint?? The call center agents are poorly trained , their senior consultants they escalate complaints to are lazy and full of excuses. After doing the bare minnimum they close the query and leave you in the dark. I'm told in the beginning of the call, which takes 20 minutes there's stock then 2 hours after the application i get an email that there's no stock. So 100 xbox ran out in 20 minutes?? Don't you add the device while you are doing the application?? Take the ****** Xbox of your website since you not making it available to consumers!
