First Class all round!

I don't use Mr Memory frequently but have bought from them for many years when upgrading my (and extended friends and family's) various computers or replacing hard drives. I have never had cause to contact them outside of the normal process because a) everything has always been spot on and b) I haven't been a numpty before and ordered the wrong thing! So the most recent transaction with them has been a wholly enjoyable experience and totally different from any other contact I have had with any other company.
I ordered PC memory, when I should have ordered laptop memory -totally my fault! - and upon completing the returns details (which is all free post by the way!) I received an email from a wonderful person named Zoe, who happens to be Head of Operations, within 30 minutes giving me a return reference and asking what I wanted to exchange it for (the return request was for replacement not refund).
I replied with my brain fart issue and stated the laptop memory needed.
I received a very fast reply stating the laptop memory will not be in stock until the following Monday.
I then - being the awkward customer I am - asked if it could be posted to a different address as I was on a bit of a time crunch. Zoe replied saying it wouldn't be a problem. I then asked how I could pay the (very small amount) difference..... and she replied saying that they wouldn't charge any more than I had already paid!
If anyone out there doesn't agree about the absolute first class customer focus and service after hearing all my issues and stupidity that Zoe dealt with....
I have no words!
Thank you Zoe and Mr Memory, I am very glad I purchase hardware from you and will continue to do so!
