Appalling service

I placed an order online on the home website on 27 April. I received an email to say that my order will only be delivered during lock down 3. I cancelled the order because I cannot wait until lock 3.and asked for a refund to be done to the card that I used. I received an email to confirm that my order has been cancelled. A few hours later I received an email with a voucher to use at the store. I did not ask for a voucher. I asked for a refund. The website clearly states that we could cancel orders during lockdown and will receive a full refund to the card payment used. I have still not heard back after almost 20 emails.

Mr Price Home. I need a refund and not a voucher.
