At times, when you buy a product online and it is defective / not working as expected, the online store will compensate you by offering the following:
1. Refund – with no compensation for the inconvenience you have faced while ordering the item
2. Gift voucher – you are obliged to spend an equivalent amount at the store, despite having an unpleasant shopping experience
The unlucky buyer has to spend time and money returning the item, and if the timelines / procedure for refund are not clear, it is better to keep the defective item and try to get it repaired locally.
