Piyali purchased an ISI marked Heater from Bharti Appliances. She made Cash Payment. But failed to get a Cash Memo. While making use of the heater she observed that it was not working properly. She contacted the shopkeeper immediately and told him the problem. Shop keeper paid no heed to her complaint. Rather he marked that the good in question was not bought from his shop. Piyali had no evidence of proving that the heater was purchased from his shop only. She discussed the problem with her friend Sohini who advised her to approach Consumer Forum and lodge the complaint. Piyali was convinced with the idea of lodging the complaint against the shopkeeper but due to lack of cash memo it was difficult for her to proceed.
