Line cancelled without approval.

Will not go on in detail, but queried a forced price increase and data increase. They insisted it was an Octotel increase and they only provided 100/100 lines, yet on the MWeb website there are still lower speeds, at lower pricing available, including the 75/75 line I was currently on. So why the forced update. Agent I spoke to could not answer my queries, Hotsun Gedeba, and after I asked about how cancelation works, he canceled my account without approval and hung up.
