Why does Verizon not offer loyalty programs like other Carriers. This customer will be switching and telling people to stay away
Telling people to stay away because a carrier does not meet YOUR needs does not mean that Verizon is not meeting the needs of others.
You should ALWAYS go with the provider which is the best fit for YOUR needs. YOUR needs are not necessarily the same as others. Others should choose the provider which is the best fit for THEIR needs. Someone basing their choice of providers on YOUR unhappiness with Verizon will just as likely cause them to be unhappy with the provider YOU choose based upon YOUR needs, not theirs, and then just as likely result in a diminished view of your judgement in their eyes.
Not everyone feels the same with Verizon, AT&T, Sprint, T-Mobile, etc... There are people EXTREMELY unhappy with each and every one of those providers. There are also people EXTREMELY happy with each and every one of those providers.
