Iwyze poor customer care service

I was looking for car insurance. I must admit it came affordable but the problem is that when I was looking for car insurance my vehicle was still at the dealership. Iwyze proceeded to deduct premium even though I had not signed any car documents as the vehicle was still at the delearship. I contacted Iwyze and eventually managed to get hold . The policy was cancelled on 03/06/2020 and I was informed that they would refund me within five days.Till to date there has been no refund. I visited old mutual branch in BT Ngebs Mthatha to contact Iwyze on 26 June 2020. The person whom I spoke to telephonically promised that they were going to request a consultant to contact me. Thus far there has been no follow up and no refund.
