Cancel numbers instead of converting to prepaid

I requested my contract be cancelled as I was due for a renewal. On 24 September both my phone numbers were disconnected. Never did I state that the numbers should be cancelled just the contracts. I e-mailed the retentions department but I am still waiting for feedback. I am still using the numbers. It is also unfair that all our minutes are now gone and we paid for the month. This is a *******. I am not even starting on the disappearing airtime on my current prepaid.
