Walmart Family Mobile Unethical Practices and Unbelievably Bad Customer Service Nationwide

In April I signed up for the Walmart Family Mobile plan. After trying to make it work for a few weeks, I was very disappointed with the substandard coverage and the service and decided to cancel the plan. After calling customer service and explaining my situation multiple times to a service agent that was confused and unreceptive, I was told that I could proceed and pay off my bill over the phone. 

I paid the bill using my credit card, and was told by the representative that I would receive no further fees and that my account would be closed. I thought the issue was resolved until I received a bill for $5.00. Confused, I called the company to find out why I was being charged. After speaking with yet another confused and robotic "customer service" agent, I was informed that the $5 fee was a processing fee for my previous payment, and that in order to avoid another $5.00 fee I needed to pay $10.00 now. I was informed that if I did not pay the $10.00, I would receive a perpetual cycle of $5.00 processing fees for the foreseeable future. 

When I questioned the agent as to why I was not informed of this $5.00 fee when I made my initial payment so that I could avoid the additional $5.00, I was again greeted with confusion and a total lack of care. 

I proceeded to write to their customer service via email, and again received no assistance. I am beyond dissapointed and frustrated with this company. I feel that their practices are unethical and I cannot believe they are still in business. Very very disappointed with this service.
