Did Vodacom cancel my contract?

Okay I pay my contract every month, not the same time but November's payment get paid in full in November etc. No worries and have been doing so for about 5 years now.

Yearend is always a bugger up even when there is money. End of 2012 was very bad for me and I didn't get all my pay (long story...), I paid most of the angry people (MFC, Edgars, Woolies & the CC's ofcourse ;)).
Vodacom was missed.

Again, in the past I have missed a monthly payment but paid asap, usually with outgoing calls blocked (you phone me, I can't phone you back, right) - the grace period was about till middle next month, then the service got suspended and you get rerouted to VC to make arrangements etc. (happened to me once in July).

I paid November, no worries. Missed December (eish) but decided, that going on previous years' doings I can pay once I get back to work (today).
HA!

Trying to phone 121 I get a "Not registered on network" error message (not voice prompt).
Phoning myself I get "The number does not exist" message.
I can't even log into the Vodacom website!!!

I can visit a Vodacom4U store tomorrow but hell, this is the first time they've been this aggro.
