- RM7840L1075 Great Service - Early AM
-
I just wanted to thank you very much for the service I received yesterday on this item, RM7840L1075.
I called late in the day, needing the part next day, early am delivery. I was assured by the two professional people I spoke with that I would get it on time, (but I really had doubts). However, just as promised UPS showed up at 7:30 and by 8:00 am the part RM7840L1075 was installed and we were back up and running.
Being in the service business, I know sometimes the customer has expectations, but doesn’t always leave you with many options, as I did in this case. But your company was able to exceed my expectations.
Again I just wanted to say thank you very much. (Posted on 4/8/2015)
