Two Different stories when two people cancel

Called in at 8:30am to cancel contract. Was advised that I will forfeit all airtime after the 30th then why am I paying in December how can I lose what I have paid?<br> But my husband called 30 minutes earlier and his airtime will be carried over in January but data will be lost. <br> How can we get two different stories. The person on the line refused for me to speak to management. I asked to cancel from the 14th of December but my sms said the 30th December. Please could I get decent service from someone who can give me correct information. In actual fact due to my lack of signal and all previous complaints I was asked to cancel my contract a few months ago with no pentalities due to me not being able to make full use of my contact. Then I try to do this the same time as my husband and this is what I get. This is not on.
