Negative Review gone wrong

This morning I received a text message from Xfinity asking for a survey regarding my service with Xfinity yesterday. I scored my service as a 0 based on my last dealing with Xfinity late last night, not my in-store visit. However. although my comments strictly states my in-store visit was good...this score is negatively gone against the store.

How can I rectify this and ensure that the score reflects my Online Chat experience ONLY, not my in-store experience...which was in all honesty, amazing!

With kind regards,
Andrew
