Purple services refusing refund after negligence from their side

This could be considered more of a dispute for some and not on the lines of scamming, I disagree cause of the following:

On the recommendation of the admin in the Purple Discord, I requested an English-speaking communicator who was flexible enough to complete skilling on one of my accounts. The admin specifically recommended this worker, mentioning that he had previously completed megascales for me and had collateral, so I trusted that recommendation and agreed to proceed.

The service did not start well. The worker had not properly read the ticket instructions.

A short while later, within roughly 10 minutes, he requested two authenticator codes. This immediately raised concerns because I have previously experienced workers outsourcing services to cheaper third parties without informing me, leaving me with no idea who actually has access to my account. I asked him directly whether this was happening, and he assured me that it was not and told me not to worry.

Today, on 9 July, I noticed that my account was logged in while the worker was offline on Discord. I attempted to contact him through direct messages and by tagging him in the service ticket, but I received no response. I then checked the Dink bot logs and noticed there was no login notification despite my account clearly being online. This strongly suggested that someone else had logged into my account without my knowledge. I immediately changed my Jagex password and forced the individual off the account.

This is the second time I have experienced this type of issue. I deliberately chose this Discord because it charges higher prices and presents itself as offering a more trustworthy and professional service. Instead, I have once again found myself in a situation where someone other than the assigned worker appears to have accessed my account without my knowledge or consent.

Because of this breach of trust, I no longer have confidence in allowing Purple services team to continue servicing my account. I requested a refund for the remaining work, but I was informed that only 50% of the unused balance would be refunded.

I do not believe that is an appropriate resolution. The issue is not that I simply changed my mind about the service—it is that their service failed to meet the standard that was promised. The assigned worker neglected the trust placed in him, and their business failed to provide the secure and professional service I paid for. As a result, I am requesting a full refund of the remaining balance for the unfinished work, as I can no longer reasonably trust their service with my account.

Can an admin block out the links to be viewed by outsiders
