Hi Popgun,
Sorry I cant help with an alternative, but I’m spotting a pattern here.
I’m in exactly the same position. Ordered and paid from the same place as you on the 12th March. No spring, or reply to numerous emails. Whilst I understand that these are difficult times, there is really no excuse for the lack of service or communication.
I also requested a refund from PP, but have yet to receive a reply.
