Sjr Primecorp — Not refunding excess amount charged for maintenance

Address:

sarjapur road, bangalore

I purchased SJR property. They have charged 30k extra for maintenance which they said will refund after registry. Registry was done on 1st sep, but still they have not refunded the money. Everyday they come up with new excuse. Now they have stopped picking calls also. I have their mail confirmation for refund but they haven't refund it yet.
