bank feeds accidentally deleted per QBO tech support

how can i get technical support when i already have a case number from my call-in yesterday?  my bank feeds stopped working, and as a "solution" yesterday one tech person had me do something that caused all of my bank accounts to disappear !!!  i have used QB for decades and loved it. today, not so much. yesterday they said i would get a call-back from their engineers, but by the time the call came in i was unable to take the call. did they leave a voicemail?.  no. an email?  no.  i basically had to start all over again today, even though i have a case number - that is apparently meaningless because here i am again today sitting on hold for hours just to hopefully get through to someone who can help - someone who will take my case number and give me some answers. I don’t trust their “call-back” request offer either.
