Ordered 5 boxes of this item. I received 5 sets of 5 strings, not 5 boxes. I sent them back for a replacement. Received 1 set of 5 strings with the number (5) and part number on the outer plastic cap. Called Revain support. We were told they would send a call to return this defective order and ship the original order of 5 boxes of 60 strings by the end of August. I received an email saying I received a $5.08 refund for my original $25.40 order. PISS POUR SERVICE AND PRODUCTS. I will go through VISA and cancel the order as it has been out of stock for over 3 weeks!
