Poor customer service all round

Poor service, poor communication. Website stated 4 to 6 days lead time. There was no communication for more than a week. Sent an email to Sell SA. Said they will follow up with the supplier. A few days later I emailed again to ask for feedback. Got an email stating order Cancelled. Supplier didn't have stock of both items that were ordered. Why isn't stock updated on the website? Aren't they supposed to notify customers instead of keeping us waiting. If I didn't email, I would still be waiting on my goods. Total waste of time!
