OnStar OnStar needs to STOP BILLING ME! Warren MI

My simplified consumer nightmare dealing with OnStar:

OnStar updated to a 5g network making them non-compatible to my needs.

October 26th 2022 cancelled OnStar services to cease end of December 2022 via 800# cancellation phone conversation.

In January both my Wife’s and my credit cards were charged a $15 fee for OnStar services (total $30).

I called OnStar 800# and was told billing would cease and would get refund.  OK.

In February cards had no refund and again billed $15ea.  (OnStar now owes $60)

I filed formal complaint with the BBB prompting OnStar to call me informing me that they would stop the billing and refund my $60.  Trusting that they complied I closed the BBB complaint (my mistake).

 In March, no refund, Wife’s card charged $15, my card charged $14. (OnStar now owes $89). 

Mid April I called OnStar cancellation 800# again and was informed that they would stop billing me plus I would get a refund of $90?  BTW: I recorded this conversation (and will continue recording in the future).

 I will be awaiting my credit card statement in May to see what develops.

They are not willing to share an E-mail address and many times stated that they only work thru social media (too unsecured for me).  They suggested I share account # and VIN # over social media (FaceBook & Twitter) (screen shots of DM correspondence acquired for future YouTube informational video). 

To OnStar; Just STOP BILLING ME!  I do NOT have a smart phone and cannot even use your services, just E-mail me since I cannot work thru social media sites.

P.S.  if you do some simple searching for OnStar billing issues you will find many complaints similar to mine.
