by separate email we just have re-sent the invoice mentioned in your email.
Please note that the invoice refers to RMA No. 1051689 (exchange of a Quartz Control Plate=QCP). The corresponding defective QCP has been received by us these days (your Ref. Invoice/Packing List No. R2014033 dated 28.10.14). Therefore we will issue a Credit Note showing the same amount as the invoice, i.e. the invoice does not need to be balanced anymore.
