No Respons on emails or SMS's

I have tried on several occasions, via Sms and emails to cancel my insurance on a hom eloan. no one come backs on my SMS in the 24 hours as promised and I had no feedback on several emails I sent to their customer service address. <br> <br> I first of all had gotten wrong info from their call center a couple of months ago and now when I finally want to talk to someone, I cant get thru to the call center, SMS, email option on website or emails to the customer care.<br> My debit order has gone off once again this last month and it could have been prevented.
