I have had Sprint cell service for about 10 years and over the last two years the service has gotten terrible. Between the lack of signal and dropped calls I never know when I'll be able to finish a conversation.
I've been trying to get a resolution to the issue and as of this month I've been working on it for 10 months.
I've had my 2 phones in to the service center 3 times each and had whatever updates done that were needed and it actually made it worse.
I was even told by one of the sales people that our phones were out of date even though they still had the same phones on display. Sprint will give you the runaround for hours if you try to get this issue resolved, they have no concept of what they're doing.
