Yeah generally its 3 - 5 days response time.
My original enquiry span over 2 days, eventually between online chat and phone calls I managed to speak to an English guy and then the process started to move. Nothing against overseas operatives but A, you can hardly hear them, B you can hardly understand them, C they haven't a clue what your trying to describe and D they want to get rid of you and pass you on to another department as soon as you connect.
So I missed a call they were supposed to give me and I emailed them my address, my serial/part number, invoice and colour of my copoer buds.
Received black sleeves!
Emailed again, had a response yesterday........tic toc again lol
