Adidas does not refund

Adidas does not refund your money, even after they cancel your order. so what happened is: Purchased items from Adidas online in December. A few days later I was informed that 1 of the items is out of stock and a refund would be issued within 7 days. after 7 days no refund, I contacted Adidas and they told me wait 14 days not 7 days. After 14 days still no refund, I contacted Adidas and they asked for my bank statement. I submitted my bank statement. They apologized and advised that the refund would be processed and I need to wait 7 days. refund reference provided to me by Adidas. Again no refund, contacted them again, then they responded saying that they did not charge me the full amount and I will not get a refund. Contacted Adidas again, provided order number, refund reference and bank statements again. they said it was a mistake and they will escalate the matter. Received another email stating that a refund will be processed. Till today I have not received my money back. this is almost 2 months and still no proper response from Adidas. the call centre takes ages to answer the call and when you do speak to them, they cannot provide any answers. you cannot speak to finance directly. there is no manager or person to take over the matter and provide support. please people, DO NOT BUY FROM THEM. the customer service is the worst that you will ever experience.
