My phone started dropping calls in my house about a month ago. How can I fix this?

Question

My wife's 4 and my daughters 5C did the same. I called customer service and was essentially told "too bad, if it's in your house we can't really help that". My wife was able to call *228 and her phone now gets 3 bars which isn't good, but its better than not being able to use her phone. My daughter and I can't use *228. We have powered off and back on, removed SIM cards, what else can we do to actually get phone service on 2 of 3 phones in our own home? The phones also drop calls around the corner from our house so it's not just in our home. The phones all work well at school and our jobs.  We live in zip code 80525. Help please!

Answer 1

I was not given a ticket number when I called customer service. I was only told the same thing you typed....  "We are unable to guarantee indoor service due to multiple factors that can impact wireless signals with structural interference ranking high on the list; However, other customers are taking advantage of Network Extenders to improve indoor service". I am starting to feel like this is a ploy to get your customers to spend more money. Most reliable network and we have no coverage in a suburban neighborhood??? Hmmmmmm.
As I said in my original post it is not just dropping calls in our home. It is around the corner from our house and in several other areas of the neighborhood, almost clustered to the south end of our neighborhood with the worst being in our home. We have lived here almost a year and had no problems until a few weeks ago. None of our phones have difficulty with calls dropping anywhere else but our neighborhood. It also effects facetime and my wife being able to send picture messages on her iphone 4. 
My brother in law has a Samsung Galaxy--on our plan--and came over last night. He said as soon as he gets in our neighborhood his phone varies greatly between 1x and 4G coverage and likes to drop calls.
The only solution proposed by customer service was to shell out $200.00 for a network extender. Again this is not JUST in our home, though it is worst in our home. This is obviously a recent network problem and should not incur a cost on our part to fix it, if we can't make a call until we leave the entire subdivision.
We will be asking people with other carriers to try their phones in our neighborhood. If they have better coverage, our family will be changing carriers. We have been loyal Verizon customers since 1999. Our loyalty ends when we shell out $300 + a month for phones we are unable to even use in our home or our neighborhood. Hoping for a real answer from customer service soon. This generic "we want you to be satisfied and have a great experience" response followed by "Spend more money with us to get coverage that you have had for a year but suddenly don't have" is unacceptable.
