MTN 1 DAY UNCAPPED - But taking from my 1 gig bundle.

Second complaint on this issue.

I bought a 1 Day uncapped bundle on Saturday 17/03/2018. After activating the bundle at +/- 10am I started using it and noticed that it's taking from my 1gig bundle and I called in to MTN and they said they will investigate. I requested a refund and was told by an agent in the 808 department that a manager will call me, I'm still waiting for the call. All I was told is to not utilize the bundle until MTN has investigated. I later realized that the uncapped bundle had been removed from my account as well. I would like to request a full refund as I was unable to use the bundle.
