Mtn Sucks

I purchased data from the my mtn app on Wednesday, I am not able to use it. I called the customer service 8 times since yesterday and no one is able to assist. Every time I call the agent gives me a different response to why the data is not work. They even told me to visit an mtn store for them to assist me. I don't have the time or even want to do that as I feel it is a problem from their side and they should be able to assist me. The last consultant I spoke to even had the nerve to raise his voice at me. After today I truly believe the consultants do not know what they are doing. Very disappointed at the service I received. P.S my problem is still not sorted out.
