Stalking Innocent People

I have called in specifically to update my alternative work number so that you can reach me whenever I’m unavailable on my personal number. However, you continue contacting my previous manager despite me providing you with the correct alternative contact details.

Does it really make sense to keep calling a number where you know you will no longer find me, while I have already provided you with the correct number to use? Kindly update your records and ensure that the correct alternative number is used going forward.
