I have been incorrectly charged more than $140 in international roaming fees. When I travelled to HongKong, I used my phone data just once to get some info. It could not have been more than few MB. But next day, it shows my charges as $140+ with 1 GB of data used.
I called xfinity mobile, they transferred me to international roaming dept. Agent took his time and said those were incorrect charges and would issue a refund. It's been 2 months and 4-5 calls and I still haven't got a refund.
Anyone else facing this? How do I dispute this?
