Bad Customer Service from Germany Spares West

On the 18th December 2019 I bought an alternator for LE9 engine. When I got home I noticed that the fitting brackets were not the same. I took pictures of the broken alternator and sent them to Jacky the sales person and notified her on the 19th December 2019 that I am on my way to return the part. I asked her to look for the correct part for me when I arrived at their auto Spares. Unfortunately they couldn't get the correct part that I was looking for and she asked to complete a refund form and provide them with my banking details. I was told that it will take 3 days for the refund to reflect in my bank account. Three days passed and I followed up with them and I was told they are working on it. Todate I haven't received my refund. This is a very bad customer service that I have ever come across in my entire life especially in an automotive industry.
