4 Days later and i'm still waiting on the Manager

I previously complained that MTN had sold me a product, and had failed to deliver on what it promised. In short they advertised the one thing, had me sign up to a contract and then delivered something else. I upgraded 2 contracts, in both instances the same app****.

After having logged my complaint on this forum, I had the Regional Manager call me. He promised he would get this issue resolved, and would provide feedback later that afternoon. This call I received on the 11th April at 10:30 am. Today being 4 days later, I'm still waiting....
