Vodacom have not cancelled pay as you go

I cancelled my Vodacom contract as I had moved to London but I was on a Pay As You Go for 1 month. I cancelled this pay as you go at the end of December, yet Vodacom (Voda****) still billed me for this and had since sent a summons demanding payment. I sent an email to customercare which was ignored.

That place is run by a team of inept *****s with a severe lack of communication and are indeed a bunch of sa, pathetic little losers posing as an efficient service provider.

I would like an answer to my query to confirm the following. Let's see if you're able to do a simple task.

1) The Pay as you go, contract and all business with you for my number has been cancelled.

2) I do not owe you any money, nor will you ask me for more money as I have cancelled

I need to be sure that my pay as you go and all business with you is cancelled as I have stopped paying for all services for my pay as you go from December. Begrudingly I paid the summons to leave me alone but who knows if you have actually cancelled my account. Please email me as I am overseas.
