how do i put guarenteed shipping on my ebay listings

If it hasn't happened to you as yet, it probably will, so just wanted to put this out there. Anyone else having this problem, please contact eBay, maybe they'll listen (ha ha) if more people bring this subject up. NO, the answer SHOULD BE (and I told them this repeatedly) that instead of saying 'GUARANTEED DELIVERY DATE' it should say 'ESTIMATED DELIVERY DATE', especially since I don't participate/am not opted into the Guaranteed delivery program.

And again eBay's answer is 'just change your handling time'. My hands are tied, I did ship within my 1 day timeframe (have proof) but yet here I am. In this recent instance, the buyer is new to eBay, & sees that date in their order details, & even though they can see according to USPS that there has been a delay in delivery (so states at ), they are upset w/me because they don't have it. But the unfortunate consequences you become subject to when you have a package that doesn't deliver by this pre-determined date (over which I've no control), the buyer writes you & is upset about it, & you have to go into this lengthy explanation & worry about retribution from the buyer because of something you have no control over. I work my butt off to pack/ship stuff & keep within my given time frame, but feel the discount is worth it. Well if I do that, I LOSE my 10% final value fee discount on my monthly invoice (as you only get that discount for choosing & sticking to the 1 day handling time you offer). They told me it is because it is pre-determined based on my handling time (which has always been ship within 1 business day), and is placed there & there is NOTHING I can do about it, lest I change/extend my handling time.

What I don't understand (and yes I called eBay about it again this morning) is why they show 'Guaranteed Delivery' date for my shipments even though I don't participate. I DO NOT PARTCIPATE in the eBay Guaranteed Delivery Program, it is & always has been checked 'NO' in my site preferences.
