Appalling Service

I've cancelled my car insurance with Santam more than 2 weeks ago & when I initially cancelled the call centre agent named Waheeda advised that the debit will still go through and she will ask for a refund to be processed it's now over 2 weeks and I've been calling almost everyday for my money to be returned and I get the same response everytime that they'll get someone from cancellations to call me back I've since been waiting and when I ask to be transferred to the cancellations department they tell me that they don't take calls. I'm really disgusted by Santam's service.
