I just discovered that Sprint automatically charges you for texting you their own commercial messages. I found this so outrageous, because text charges are not itemized on your bill.
I asked to have it stopped and they offered to automatically block all text from my phone. While this was fine for me, I wondered what would happen to people who actually use text. After I inquired, they explained that they were able to only block Sprint commercials, allowing you to continue regular texting. Why didn't they offer this initially? And why do they automatically charge you to text you their own damn advertising?!
Also, several months ago I realized that they were charging me $15/month extra for Vison Pack for each line (that's $30/mo.) I asked to have them remove it from my package and from the bill and they assured me they would. It appeared again the next month. I called again. Then it appeared the following month. This time I threatened legal action, and I insisted they send an email confirmation. Finally it was over, but I was furious thinking about all the people who do not vigilantly check their bill each month like I do. They are unethical at the least. If you use Sprint, proceed with caution!
