My business postal code had recently changed from k6h5r5 to K6h7r7. I went and updated Google My Business and all the places where my business is listed.
However, I realized that Google keeps the old one (k6h5r5). I tried many times to change it there but without success.
Keeping in mind that this change is not affecting the mail delivery, should I go and change everything back to k6h5r5?
