cancelled without my knowledge

I upgraded my telkom to the 40 gig package last week. They should have delivered before 12:00 on Monday as per courier who arranged for 12:00 only to arrive at office at 3pm at which point I was already out to see clients. Today they delivered package without arranging a time with me so I wasn't at office at the time. I never went back to office as per full day seeing clients. Tonight when I tried connecting with my month to month contract which I topped up with another 5 gigs last night wouldn't connect. I called customer support and they informed me that month to month was cancelled. I was never called today to ask if I received new package and if it's okay to cancel or migrate the number to new device. Now I have work to do and emails to send but no Internet connection. I feel the service I received is very poor as per following up and feedback from 8ta. Never was I informed that old contract would expire right away as it's the 17th and it was topped up with another 5 gigs last night. I'll be looking for another service provider as this is poor service. Desmond at support centre was only one willing to help as two ladies I spoke to before that didn't even as for my ID to check
