I wont go away

I bought a cluster for a Fiat Punto and paid for it, the item was sent timorously and I was super impressed with the process and the service. Sadly when fitting the cluster it was completely dead and unresponsive, I called to advise them and ask about the process of getting a refund. I sent the unit back by courier and awaited my refund, Britz Brothers went into hiding, no one was taking my calls until I posted a complain through their preferred WhatsApp forum as well as a review, which seemed to evoke some action as I got an email from Ryan apologising for the issue and advising me that a refund would be made the following Tuesday. Needless to say, Nada, nothing. I have tried again in vain having sent at least four emails each one about a month apart to Ryan (the contact that is supp**** on the web) to no avail, not even the curtesy of a response. Yesterday I finally got hold of someone and was told to Call Mariska, guess what that phone is never answered. Maybe its because I sent an online review that I have become persona non grata. None the less I am owed money. They have the returned part as well as the money I paid initially. Shame on them. Sadly this squeaky wheel isn't going anywhere. I am persistent if nothing else. Prepare to see the next chapter of this unfortunate incident.
