REJECTION OF ALTERNATIVE PRODUCT SUGGESTION
We regret that our order for [PRODUCT (S), ex. five A45 compressors] was not able to be fulfilled due to [REASON, ex. a large backlog]. Although I appreciate your suggesting, [PRODUCT (S), ex. the B45] as an alternative, I’m afraid [STATE REASON FOR REFUSAL, ex. that model lacks the level of throughput we require].
[EITHER ASK FOR ANOTHER SUGGESTION, OR MENTION THAT YOU DO NOT REQUIRE ANY OTHER PRODUCTS, ex. Unfortunately, we were forced to place an order for the A45 with another supplier. However, we do look forward to dealing with you in the future. ALTERNATIVE: Would you have a similar compressor with a minimum throughput of 650 cubic feet per second? Please contact me at XXX-XX-XX at your earliest convenience.]
