Bad customer service from TFG ONLINE

I bought clothes online for my daughter last month on TFG ONLINE and i waited for delivery which i didn't get instead i got a refund sms without anyone calling me to explain whats going when i send them an email asking about my order they said they had no stock of the items how do you take customer's money without checking stock availability i was so angry because i had plans with my baby this week for her to wear those clothes im very dissatisfied with their customer service till today no one has called me to apologize or anything i have used online shopping before with other store and never experienced such bad customer service i gues i should just delete this stupid tfg app on my phone since its not working for me.
