Terrible Customer Service

I ordered a pair of shoes and a Hoodie, which they wer delivered on time, unfortunately the shoes didn't fit, I requested a return which ws approved and chose another shoes of the same amount. The Courier Guy (***********) took forever to collect until I requested to speak to the manager, then the Parcel ws collected. It's been 6days since the shoes have been collected, I tried reaching out to Under Armour for an Update , Bt no one is responding, send numerous Emails, even requested Customer complaints Manager, but still no answer, Disappointment is an Understatement, cos my Gym Routine hv been inconvenienced, cos I don't hv training shoes, it's been a Month without going to Gym now, paid a monthly fee for nothing, thanks to the *********** Unprofessional Under Armour. I love the Brand, Bt I m not going to beg For Standard service, I AM resorting to Alternative Brands. I want nothing to do with the Brand, my Colleagues, Family, Church Members and Social Media @Large are going to know about this, maybe if they lose customers it will give them a Wake up call and make them realise there s nothing Special about UA
