Returned pod

I returned my pod in February, tracking states it was received on the 19th, to date I have still not received my £10 refund.
My email address was on the outer packaging as well as the pod box. I have contacted customer service and given the invoice and order number but despite chasing I have had no response.

Hi, have you received your deposit back yet? I’ve been trying to get in touch about when I’ll receive mine but not received a response either by email or via messenger :grimacing:

Hi,
Yes I did, took a while to get it and a few emails. Keep contacting them and hopefully you’ll get it back soon.

That’s somewhat reassuring but I’m wondering if I’m going to have to initiate a credit card charge back. I find the change in responsiveness to messages really odd…
