Fixing the workflow, vendor2client and vendor2vendor relations?

The company I work for is the biggest vendor providing IT services for some big retail company. We develop e-commerce sites for different brands they own and indicated countries.

Recently, the global QA team asked us to prepare "unit tests" for each of the stories. What we we're actually asked to do, was to go trough each feature's functionality on actual live site of this brand on indicated country, and prepare an excel file including a description of each "unit test" understood as "functionality description". Now, when we are implementing each feature, we have to go through each "unit test" and taking screenshots of each result for each of the language version, both for PC and mobile. They claimed it to be necessary to lower the number of bugs reported. The thing is, as a result we spent much more time on our tickets, but the number of bugs reported is not really lower. QA team often doubles the the tickets reports of the same bug, and sometimes they seem not to pay attention to what is happening on out Kanban board and in tickets' comments. They sometimes make us work with people who have almost no experience in IT field.

Also, the client made us report time spent working "per ticket", we did that "per project" before. They want us to learn new technology and won't pay for that, but prioritize projects' progress more. As a result, we can learn only if there is no work on the project at the moment. The other vendors we work with often delay completing their tasks claiming "they're busy".

What can we suggest to them as an alternative to this? Any idea is welcome. We can not leave this client. We work in SAFe if that matters. Thanks in advance 🙂
