T-Mobile is frauding and charging for international calls made on wifi

I have been noticing increases on my monthly bill life $180 and called in to verify. The agent  told me the extra charge is due to an international call. But guess what: I have been calling my Spain for years using WhatsApp Call and I have never been charged, since I have unlimited data. When I google the question I realize I'm not the only one who has this problem with T-Mobile. On my first call to the billing department the agent told me that international phone calls made through WhatsApp can be charged; Customer service didn't want to remove charges so I will be transferring my business to AT&T. I even visited the store here in Dadeland and manager will no remove the charges. They rather loose business, incredible.

I am getting charged for international calls when using WiFi. T-Mobile Support claim I must have dropped off wifi and was picked up by a cell tower hence the charge. I have pointed out to Customer Support that the bill details show a 'W' which indicated a WiFi call but I'm still getting billed, same support answer. In fact support went as far as to suggest I have been very lucky not being billed for all international calls! After 9 years and roaming the world with T-Mobile and religiously using WiFi I am noticing billing occurrences are more frequent this year. Maybe they can cover under the excuse for some calls, but I cannot fathom how they can justify billing when they indicate it's a WiFi call on the bill!
