@brerrabbit585There's a little question mark at the end of the above bit and if anyone clicks on it they see this:Delivery time is estimated using our proprietary method which is based on the buyer's proximity to the item location, the postage service selected, the seller's postage history, and other factors. Delivery times may vary, especially during peak periods.Anyone with half a brain should know they're only approximate dates, even without reading the extra bit above.
Hah ... confession time! 17 years on Ebay and I've never noticed the little (being the operative word with my eyesight) question mark.
Thankfully I know the meaning of 'estimate' and am relieved to know I have at least half a brain!

I know this particular issue is already resolved, but I thought I'd post this on the chance you find it helpful in the future.
One of the best things I ever did, after experiencing a few problem transactions and feeling a bit flustered from not quite knowing how to handle it or even what my response should be, was to sit down and work out exactly what I am prepared to provide as a solution in specific circumstances, and also wrote out a few message templates that could be adjusted / edited as needed.
Doing that meant I didn't have to ask my self "what do I do here", because I'd already decided, and the message templates meant I could copy/paste a reply, customise it, and respond within a few minutes if I was already at the computer (which I personally feel added an element of authority to my response - I tried to craft my messages so that they were polite but firm, empathetic but not excessively apologetic, and avoided anything remotely accusatory, unless it became necessary but even then I framed it as tactfully as possible).
You'll sometimes get buyers that keep trying to push, but having answers / plans at the ready can help increase the confidence in your actions, and I think that shows in communications, and over the years I've found it's usually only the ones who were determined to cause trouble from the start who won't be swayed by confident, reasonable and firm responses (these buyers will just outright ignore what you say, won't answer your questions, and insist on whatever it is they want to insist upon - in those cases I just repeat the most important points, like what options are available, and tell them the matter can't be discussed further. In really extreme cases, which thankfully I've only had 3 in 7 years, I will advise them of an account manager's decision, which is final, just leaving out the bit that my account manager is me.... 
).
These don't have to be stated policies that buyers can read, just things that you can refer to for situations that can't really be covered in detail in your terms, like what you'd do / say if a buyer asks to return something outside of your return policy, or if they say you sent them the wrong product when you know you sent the correct one. They don't need to be inflexible, either, as I'll often bend my internal policies for a buyer if I feel the situation warrants it (sometimes all they need to be is a little more polite and respectful than the average buyer - eg I just accepted a change of mind return 6 weeks after the sale without hesitation [I knew the product was unused], while I have declined requests a few days after my timeframe because I knew they weren't being honest and had purchased customised items to wear to an event).
