At the time of signing up with T-Mobile for a family plan, I was told clearly and repeatedly that there is NO activation fee. Unfortunately, the bill shows otherwise, there is US$140 activation fee. I immediately contacted T-Mobile billing department. They declined to provide credit to my account; they told me to contact the agent instead. The matter is still unresolved after making contact to the agent. As a consumer and customer, why should I have to go through these inconvenience to fight for their elusive mistake? I strongly believe this is a policy of deception; this type of business conduct is unacceptable and detrimental... It has never been any similar painful experience with AT&T or Verizon in the past!
