Dishonest and poor customer service

I placed an order and selected Collection as the deliver method. The order was accepted and processed.

Now the order is ready for collection, but they tell me I can't collect because they are not allowing any collections due to Covid-19. I have to either arrange my own courier to go collect (why not just let me collect??) or I have to let them quote me for shipping, when I live 5minutes away. I specifically selected the Collection option because that's what I wanted, and that condition of the sale was accepted by TechnoPro.

It is dishonest to accept an order for Collection knowing that collection is not a valid option. I asked why they accepted the order and they have stopped responding to my mails. There is no answer on their phone.

Online retailers rely on trust. Good prices only go so far, they mean nothing if you don't receive your order or you don't know what condition you'll receive it in. Clearly, this business cannot be trusted.
