Ordered iphone 6 plus 0n 26/3/18 nothing happened for 9 days , I emailed the company and received a reply saying " I can confirm that your device is due for dispatch in the next 1-2 working
> days, but that I have prioritized your order to ensure that yours is the
> next to be dispatched." on 4/4/18.
10 days later nothing happened ,so I emailed them again and was told "We are sorry to inform you that we are experiencing a slight delay shipping your item out to you.
This is due to the extra quality control checks we have been required to carry out including a slight delay from the courier network in unlocking the device. I can confirm your item should be dispatched within the next 2-3 working days. You have been placed you on our priority list and as soon as your device is ready, it will be shipped right away via next day delivery.
We are sorry to inform you that we are experiencing a slight delay shipping your item out to you. "
3 days later I started a dispute through paypal and they obtained a refund. So why it took 17 days to NOT dispatch a phone I dont know.
