In one of my builds I have 4x8GB Crucial DDR3-1600 low profile ram sticks and one of the sticks decided to give out. After submitting an RMA, a Crucial rep informed me that these sticks are discontinued but he can offer the standard height DDR3-1866 (BLT8G3D1869DT1TX0) as a replacement and will replace any additional memory sticks to keep it uniform. (Nice Micron. I appreciate that). I agreed to the replacement and instead of getting the DDR3-1866 version, I got the standard height DDR3-1600 version instead. I contacted Micron back and a different rep simplify told me the same thing how the old low profile sticks are discontinued and apologize for the inconvenience but hope I have a great day. I'm not entirely upset but I informed this new rep that at the time of purchase of my ram sticks, I paid a bit of an extra premium for the low height feature over the standard height and agreed to exchange all the ram sticks for the DDR3-1866 that was originally offered. The same rep informed me that at the time I purchased these sticks were $75 and the new replacements are $85 as of today. She apologized again and told me to have a great day again. I replied back asking if it is still possible to received the DDR3-1866 as originally planned if I sent back the DDR3-1600? She hasn't replied back after 2 business days. Should I just let Micron off the hook this time? Or should I keep complaining until the give me what was originally promised?
