Poor service!!

My debit order that was supposed to go off on the 27th only went off on the 4th??? What if there were no funds available?? I changed my car insurance from momentum to outsurance. Initially I insured my new car with momentum and was charged a pro rata rate. I canceled the policy as outsurance was half the price you offered me with better benefits. I have not received any money back as the policy was canceled before month end. I phoned your offices and a "supervisor" said she would investigate. I am still waiting for feedback. More than a month. Quick to claim pro rata but lacking to pay back! If my debit orders go off again late then I will terminate ALL my policies with momentum
