My sincere apology

This is an apology to Vodacom. I have been complaining bitterly about my broadband data speeds being very very slow for about two years now. However i have just discovered that if I moved my modem outside my speeds go from 2Mb/s to 20Mb/s immediately. I am so sorry for harassing you so much. I don't understand how this happened but my speeds indoor used to be good and then overnight the signal and speeds just went bad and I assumed the fault was from your side. All I can think of is the guy upstairs moved in some heavy steel gym equipment. I dont know if that can affect my signal and speeds, but otherwise I am baffled. Sorry again for all the complaints and bad reviews.
