Hii
I had ordered an item from Decathlon worth 1698/- on 2nd of December 2020 and I had canceled the order due to delivery issue and it was done on the 3rd of December. So I waited till 10 working days for the amount to reflect in my account. Which did not happen. So I tried contacting Decathlon and they replied that they were already done with the refund transaction successfully. So later I approached my bank branch and they did not cooperate at all. Later I was able to file a chargeback through customer service on 29th of December 2020. They mentioned the amount will be credited and the issue would be resolved within 15 days. So I had to wait. Later it did not happen and today it's more than 2 months for this transaction and no response. Customer service is just giving dates but not resolving the problem. Decathlon had provided me with ARN[protected] and my complaint number with union bank of india is [protected].
Please help me with the earliest.
