I traveled to France in 2016 and put international service on my account for the 2 weeks I was traveling. I called Verizon the day after I returned (they have a record of the call) and cancelled the service and was issued a credit for not using the full months worth of service. Apparently the person who issued the credit failed to actually cancel the service and, unbeknownst to me, since I do not manage our phone bill, Verizon apparently did not cancel the service and continued to charge us $31/month for 22 months. I only found out we were being charged when I called in March of 2018 to suspend my son's phone line since he is in the military overseas. The Verizon customer service agent noticed that our bill was high and asked if I traveled a lot internationally. I do not and she was able to credit us 3 months worth at that time ($120). I then called back and spoke with a supervisor, who begrudgingly issued another 3 months worth of credit ($120), but implied it was my fault I was continuing to be charged because they send out bills and I should have caught it. I followed up with a registered letter to their headquarters, and 3 subsequent phone calls, all to no avail. Verizon should have cancelled the service when I requested it be cancelled (June 2016), but instead did not. They proceeded to charge us for 22 months, and I contend that they owe us the other 16 months worth that they charged us ($496) and will not refund. This is so wrong.
