R620 Added Raid

We have an R620 that we wanted to add raid to. So I purchased an h710 Mini perc card and noticed I would need a new cable from the motherboard to back plane. That was a week ago. I have been reaching out to my sales rep for a week. At first responses were quick, but he told me that he could not place the order. so now I am dealing with him and another rep and have been for the week. I have received 1 email of quotes for a bunch of external SAS cables. Now I should say that in my first email I included the actual Dell part number I needed. 

Why is this taking so long. Do they not want to sell me a $5 cable for $155? This is a time sensitive project and I am getting very frustrated at Dells inability to fulfill a simple order. 

Removing my complaint as it has been resolved
