MIWAY - *****ing mony!!!!!!!!!!!!!!!!!!

I have acquire short term insurance from Miway on the 13th April 2018. I have paid the pro - rata premium as required. The policy is subject to an inspection of my vehicle and the fitting of a tracking device. I have not yet taken my vehicle for an inspection but a tracking device was well fitted. Today, 02/05/2018 i phoned to cancel my policy as i was offered a cheaper premium/month from another company. The call center insisted on a 30 day notice period and said they will still deduct the monthly premium from my account. Miway!, my vehicle was not inspected by your service provider and therefore i see the contract as nil and void. Any monies deducted from my account will be paid back with 5% interest before the close of business on 3/5/2018 or i will initiate a case of ***** and/or THEFT against MIWAY!
