Piano tuner is angry with me

Context: I've played piano for a few years, but played other instruments in high school. Never got to focus on piano but have a lot of experience with music. I'm now in college and trying to focus on playing again.

I decided to get my piano tuned after years. I found a local tuner, he had a fair price of $140. There was a small discussion and all I knew was to say I wanted it at standard pitch. He asked if I played with other instruments and I said no, just standard pitch, as long as it sounds right (I didn't think my response meant I didn't want it at standard pitch). He finished, I paid him and gave a $20 tip- not much but it was the best I could do.

I've been practicing and noticed it didn't sound right. I used multiple tuning apps and played along with recordings and it wasn't at the right pitch.

I contacted him being careful with wording because I didn't want to offend him. He responded by saying he mentioned it was a higher price to "fine-tune" (I have no recollection of this) I called him and he was irritated that I didn't initially understand the difference between fine-tuning and what he did. Claimed that he told me it was an extra $50 to fine-tune and tried to gaslight me that he said all this before he tuned the piano when we literally exchanged 3 sentences the entire time he was there.

I feel ripped off bc I paid and tipped him for the wrong service. At one point he said he used his best judgement which is why he didn't tune to standard pitch. He also said "It seemed like you were on a budget" which is really out of line because at no point during our initial interaction did I mention the price or ask for a discount. I literally gave a tip so it's kinda fucked up of him to say that.

The conversation ended with him saying I don't deserve to come back and tune it, but he would come back and do it for another $50. (all of this is being said in a rude passive tone)

It's my fault for not researching the correct terminology, but I'm really upset that this was his reaction when I've been nothing but respectful. I'm a struggling college student, coming from a very low-income household (I got my piano for free from a family giving it away) so it meant a lot to save up and splurge on this. Now I don't know what to do:

- I don't want him to come back because talking to him was such a bad experience

- Getting another person to tune it is also really expensive

- I could try to tune it myself but I'm worried about breaking a string

Does anyone have any advice?? I don't know what to do :(

//Edit: OMG I did not expect this much feedback!? Thank you to everyone who took the time to share some advice!! I understand the whole situation way better than before. I hadn't tuned the piano in 5-6 years so I completely understand that it couldn't have been done in one session. That tuner was so confusing bc he said he was going to fine-tune it that same session but I apparently said no when I told him I didn't play with other instruments. That guy was wacky, but I don't feel as dissapointed anymore because you all helped me understand the reasons behind all this and how delicate the strings are(which I had no clue about 😂😂). I also had no idea if I was supposed to leave a tip, but at the end of the day I respect the craft and seriously commend all piano techs-- well all the nice ones at least haha! Thank you guys again! <3
