MiWay..... should be No Way

In July this year, after seeing a TV advert for car insurance I contacted MiWay for a quotation, the processes efficient and after some discussion the price was agreed. I paid R415 as requested. A few days later following a follow up call from one of the representatives of MiWay I realised that the policy I had agreed to was not what I understood it to be so I decided to cancel the policy. After many calls from different people some quite aggressive I again asked for the refund and to cancel the policy . Its now 15th September and still no refund, just some emails saying they had tried unsuccessfully to call me, not sure about that as the number is my mobile number and with me 24 hrs a day. Don't know what they need to call me they have my bank details, they just need to reverse the payment. (how difficult can that be).
