bad service / disastrous refund process

Bad service , i have been communicating with an employee from pc link computer in regards to buying 5 switches but 2 was confirmed to be on stock then i made payment , only after 3 days i am told the stock cannot be located at the warehouse when i have specifically spoken to the the Employee that this is not an individual buy but it is for a client , when i requested a refund i am told about 7 - 14 working days which is a very huge inconvenience to us and our client , why am i being inconvenienced and having to pay penalties for pc link incompetence ? there is another online store which i used they didn't have stock after i made payment but my refund was immediate ? we are all running a business and for you as pc link to give me what is due you want your payment to be reflecting so why put other businesses in a financial scrutiny ? , this refund process is very ridiculous as if the company is not selling technological items ? even the companies that don't have the technological capability can produce the results pc link cant. i have sent an email to as what was done for my refund to be expedited but there is no response and i believe there is also no interest from the employee to fix this issue . i have a trail of emails that have communication with pc link
