Peugeot Hatfield and Customer care

On 2018/02/15 we made an order from Peugeot for parts that were to arrive on 2018/03/09. We were promised every 15 th working day until the 18th of April 2018 that the parts will be there, yet again no part were there as promised, apparently a delay was caused because the person who ordered the parts were fired. The part were then supposed to be delivered on the 11th of may 2018-no surprise the parts were not there, so we struggled and struggled and been promised every 15th working day the part will be there until the 9th of July, this caused us to launch our first complaint at customer care- so we were promised yet again that the parts will be there in 15 working days (30th of July) we phoned customer care again and another 15 days were added, we gave them 20 working days and now all of a sudden I have been informed that the part cant be distributed because it is not being manufactured anymore. I left Head of customer care messages because you cant get hold of him i was promised he will phone me back but he did not phone me back at all. Names of staff can be given on request.
