Cancel representative-Anyone used to/ plan to cancel your representative, pls share & help

I have been experiencing terrified service provided by a Canadian immigration lawyer in Canada.

After 2 years since receiving my 1st deposit, they performed very bad causing the delay in the process. 2 years later, I had to do my own research & coached them what to do with lots of pressures and arising expenses. Finally, just got Nomination from the province. I have paid them 2 times for provincial works and decided not to continue with them for federal steps.

My question: 1) Do I have to use the form "Use of Representative" to declare Cancel Representative and send to the provincial Nominee program (which already issued nomination successfully)?
2) Do I have to attach the form "Use of Representative" to declare Cancel Representative and send to CIO when applying for PR?

Can this bad lawyer affect PNP and/ or CIC to make negative decision on my case?

I am so stressful with this lawyer for years... and still...

Thanks a lot for your sharing!
