Reliance Digital — Samsung a72 and Sony HT iv 300

I feel like stuck in between not even getting instant cancel and refund all money nor able to get the products deliver.

I brought Samsung a72 and home theater, when I book the product they told it will deliver as soon as cheque get cleared.

And it get clear on 31 March but they told they can't see clearance of cheque on their PC.

And rest is the story till now they are just making us fool.

Please help me...
