How long should people for refund?

Placed an online order on 13 June 2020 and paid for. Delivery time 2 - 5 work days.... A month later (July 2020) I got a call to be offered an alternative - and I said NO because it had no features I wanted in the laptop I bought. I was promised refund in 14 days from that day and status was changed to refund. Nothing happened I wrote them an email on 06 August 2020 to enquire on the refund. NO REPLY - NO ACTION. My email included this - "How long should I wait - am I the unlucky one? or should people go to social media to just get service. Even stores that deal in paper-based (old) technology are more predictable and reliable. This shop is selling "latest technology" but not using the same technology to process orders nor refunds."

EXTREMELY POOR SERVICE - NEVER IN MY LIFE AGAIN!!!!!!!!!! PLEASE THINK TWICE - INCREDIBLE CONNECTION OBVIOUSLY HAS TOO MUCH BUSINESS TO WORRY ABOUT NEW BUSINESS - GOOD TIMES
