Don't know if application is cancelled.

I am trying to cancel an LTE application because I wasn't told about the throttling. After 10 GB of your 50GB you get throttled at 128 kb/s! What a joke, 40GB wasted. Sales person never pointed that out. I sent her the documents before I was aware of this. Trying to get hold of her via email address, no luck. Telkom call centre not answering, 3 calls now over 30 min holding time. Not even sure if they are processing this application, but definitely won't be taking it. Sales person has gmail address which is also strange, thought documents should come from Telkom address?
