It's not completely clear what the situation is, but from what I gather it seems that you're the sender and the recipient is not acknowledging a payment you have sent.
I assume that you have verified that the credited address 1Gouzjo9Jav1k4AmRoUJJMzidVfnMoSieS matches the one that you were supposed to pay to, and that the amount matches the invoiced amount.
The address 1Gouzjo9Jav1k4AmRoUJJMzidVfnMoSieS has received 0.02661900 BTC in transaction b36157a7ca9630a88d98125fca91de81f488ef7d9a60f9e57af055d4d91f7a50. This transaction has been written to the blockchain more than a day ago and is confirmed. Given that this is the correct address, the receiver did get paid, whatever they may be claiming. Secondly, the money already got spent again which means that they must be fully aware the money arrived.
Assuming that you have paid the right address, the issue is on the receiver's end:
Either they gave you the wrong address which you paid correctly and someone else received the money (unlikely), they do not understand that they already got paid or incorrectly accounted for your payment (unlikely, since you already tried following up with them), or they're lying to you.
You should follow up with them and firmly assert that the requested address in question has been paid (after you have verified that it was the correct address) and ask them to check that their systems are working correctly. Perhaps that will prompt them to "suddenly find your payment".
Do not under any circumstances send them any more money, if they don't acknowledge that your payment has succeeded and deliver their side of your agreement. Often scammers will make up nonsense excuses to get you to pay even more money. If they do not acknowledge your payment, you may need to decide to write-off that money or sue them.
12Based on the conversation posted, this sounds like a scam. Beware anyone promising guaranteed profits after you send them Bitcoin (for ‘mining’, or whatever), it is a common scam, you will not have any ‘profits’ returned to you. – chytrik – 2019-08-11T22:28:16.733
What should I do in order to return my investment? Or to let other people informed so it will not happen to anyone. – Marc pangan – 2019-08-12T04:00:33.087
4You can ask for your money to be returned, and hope they will comply. If not, you could contact your local law enforcement, but realistically there is likely little they can do. Once a Bitcoin transaction is confirmed, there is no way to reverse it, the person you sent those Bitcoins to now has full control of them. – chytrik – 2019-08-12T04:54:43.163
3@Marcpangan What you can do? Inform yourself before jumping on obscure "invenstments". – glglgl – 2019-08-12T09:20:14.760

The person you're communicating with is a scammer. Their profile pic appears to have been stolen from https://susanin.news/longreads/padali_no_podnimalis/ You're not getting your money back.
