Waiting for refund due to incorrect charge.

On 2 Nov 2020 and 4 Nov 2020 the exact same amount was charged to my bank account by RS Components, upon further investigation I found that an invoice was issued for the same amount for 2 components I ordered (I cancelled one beforehand), that was never shipped to me (When trying to check the tracking number there are no tracking information).

So on 5 Nov 2020 I contacted RS Components and a customer representative responded. After exchanging a few emails over a few days it was determined that I was incorrectly billed and that I will be refunded. The customer representative did follow-up a few times on whether I received my refund and each time I responded that I have not received the refund.

The last follow-up was on 8 Dec 2020. The company closed for Christmas from 23 Dec 2020 to 4 Jan 2021. On 4 Jan 2021 I sent a follow-up to the customer representative and I received no response.

On 13 Jan 2021 I sent an email to their complaint email address and I have still not received a response (and this is not the first time I report something to the complaint email address and get no response). This is unacceptable.
