Worst experience by far

Worst experience ever.

Order a flat iron online, wait 2 weeks and when it finally arrives, it's not at all what I ordered. Call to tell them that I got the wrong product, takes them another week to collect this incorrect product, then they advise that I need to wait another 2-3 days for them to investigate. Why does everything take so long? I've sent pictures of the product to prove that it's the wrong stuff. Then to top it off, nobody answers any of my questions to emails or updates when required. Why am I being punished for their mistakes?
