Under Armour Canada

My experience with under armour was simply dreadful. I’ve made many purchases over the last 16 years of their products I placed an online order $189.00. Total purchase. My account was debited for an extra$88.12. I reached out by phone, got some of the most ridiculous responses, one rep even said it was my bank’s fault. Sent an emai. No response. All I asked please tell me why my account was debited in that amount, above my original purchase. Nothing. My only recourse is launch a dispute.
