THE WORST SERVICE EVER

I have a contract with MTN and I want them to add another line since week. The agent I have been speaking to Nikita has not been very helpful, apparently she is having difficulty attaching my documents and has sent the matter to MTN. This was approved on the 5th of August and to date I have been sent from pillar to post. She promised to give me feedback this morning (12 August 2020) and nothing. I am currently on hold with MTN, I want my order cancelled, the service has been absolutely ********** I hate the level of customer "care" I am receiving. To top it all off no one seems to know which department I should be sent to I am being different numbers that change with every agent. I am soooooo dissatisfied words can't even begin to describe how I feel. It can't take a week to attach documents, the silence from the agent is the WORST thing ever, call a customer when you say you will. The one star is not even the correct rating you deserve a zero
