Incorrect part supp****

purchased a starter from DCB Palmiet street in Stikland Cape Town on 01/06/23 for use on my project car a 2004 ford focus ST170 2.0L and collected the part which was fitted in the hope of starting this refurbished engine on 04 February 2024 after a considerable amount of work and time as well as money was spent to get to this point only to find the starter does not work on my car on closer inspection the part number which is on the part O331303071 is is listed for Lancia, Fiat and VW starters. I tried contacting DCB to explain the situation but was brushed aside even though the part carries the DCB serial number and date. Now I'm sitting with a part which I cannot use and paid alot for
