Customer champions that cant sort out anything

Changed to MTN data contract for my house they said yes we will get LTE speed after confirming on the map. I have called numerous times they keep resetting the number and that is not helping at all. I should not have changed over from Telkom i thought that they were bad Im paying more now for less data and even slower speeds, crazy first chance i get im closing this contract. I love how they say we are putting you through to a customer champion, i had to call 4 times today alone after having the call drop once and an extension that they said i should dial doesnt go through.
