Poor customer service

Good morning Hallo Peter my you kindly assist me I received a bad service from a company called Blinds & Shutters Direct . I requested a quotation of 4 Fluxwood blinds they came to measure the windows and then I informed them that I would like them to measure the dinning area window but I am not sure if I will be able to have enough budget if the dinning area window is added they agreed to add the window and they said if I am unable to pay the added windows they will just remove it from the quote. When I received my quote I realized that I can afford to pay the whole amount of R8 739.20 via eft. To my surprise yesterday brought a split blind for dinning area window something we never agreed upon I spoke to them yesterday when they came to fit, telephonically and via e mail just after 12 noon that I am not going to accept the dinning area window because this not what we agreed upon and I requested my full refund yesterday before end of business day to date I haven't received my money back, the Company is closing only today and their response was that they can only refund me next year. I don't understand why couldn't reverse my transaction yesterday as I asked why should I wait until next year for the service which was never rendered! Kindly interve. Kind Regards Degracia Mogari
