So i signed up to Bigpipe on 31/01/2014 and got connected on 07/02/2014. On 25/02/2014 i received an invoice from Slingshot for the 24/02/2014-23/03/2014 period. I immediately contacted slingshot support telling that that i had switched ISPs and to cancel the charges. Payment did not get cancelled and my credit card got charged on 28/02/2014. I then contacted slingshot asking for a refund and was told that they never received notice of the switch over and the no refund would be given due to them requiring 30 days notice. I guess i'm just gonna have to wear it, according to their terms and conditions they're in the right, but it still left a bad taste in my mouth. Does anyone have any experience with this situation/any (not too time consuming) avenues i could persue to get that extra months charges back?
