Hi There. I am Bing and I look forward to helping you with your issue today.
Please advise which Map services are you referring to? Such as Google Maps, Microsoft Bing Maps, Nokia Here Maps, or other mapping or navigation devices such as Tomtom?
For Google Maps, you really can't expect they could respond you or even modify the maps instantly because too many similar requests are coming to them everyday and they do need to verify every single detail before making the final changes. Mapping is a huge project, always.
Can you please clarify, are you referring to business mapping or individual correction?
