Punctuality and professionalism from the matchmakers. 
I had to follow up with my matchmaker myself most weeks to get an update because she would forget to email me (one week I did not, and so I did not hear back until I reached out the following week). I also had to remind her to schedule the monthly video calls. If I am paying 100$ for a service, I don't expect to have to do this part of the job for them. 
I know the results of the matches are out of the hands of the matchmakers, but some encouragement in the process would help. I heard that it is quite difficult to find matches from my matchmaker, and I wondered why I was enrolled then in a process that wasn't going to yield anything for me. A bit more professionalism and better communication would have made this a better experience. I loved Alisa as a person, and I especially liked catching up with her, but it was frustrating during the moments in between.
