Onstar credit card problems

[DavidVT]

Hello,

August 2020 my credit card exp date was changed. 
Every month OnStar tells me my payment has a problem. 
Every month, with gradually increasing frustration, I call and discuss this with an onstar representative. Every month I am told it will never happen again and how sorry they are..

And here we are in March and a new OnStar message arrived to tell me all the wonderful services I will loose without payment. 
Can GM properly update their credit card processing system like every other of my vendors managed to do last September??

Please refrain from insincere apologies in any reply...  🙂
