Tired of MTN and their BS

I am still waiting on mtn for the delivery of my galaxy tab active...it has been almost 2months since I upgraded to the galaxy s8 plus and was suppose to receive the galaxy tab with the upgrade but 2months later and nothing. The tab is one of the only reasons I did the upgrade plus that I am leaving for my honeymoon next week and wanted the tab to take with us but mtn store is up to s^#^#. Everytime I phone the store I upgraded at they have some form of excuse or the guy is in the bathroom and will phone me back or he is on lunch and will phone me back this has been going on for weeks and they never phone me back. But mtn is fast at the end of the month to remind you to pay your account. I am fed up now. I will not be paying my account any further as I have to pay for 2months for something I did not receive. You have the worst customer service ever.
