Lack of feedback on refund

I cancelled my Iwyze insurance policy beginning of May 2015 and was advised I would get a refund on premium (a pro-rate refund as I had been covered for the first few days of the month). I was advised this should take around 14 days. It is almost two months later - I have contacted Iwyze and was promised by the consultant that I spoke to some feedback within the next 24 hours. He took my ID number and looked up the policy number and said he would email it - he contacted me again the same day to tell me he had done what he had promised and that I should get a call. Still no call from Iwyze.
