I am still awaiting payment for an Iphone 6 I post...

I am still awaiting payment for an Iphone 6 I posted to them early August. The last contact I had was the 30th August and haven't heard anything since. I wouldn't suggest dealing with this company. I am very unhappy that the payment has not been settled and don't feel that the length of time is acceptable. Order reference AF55A1.

Update 19/9 - payment still outstanding. Not impressed
