投诉有故障的家电Letter of complaint about a faulty appliance

Dear Sir or Madam, I am writing to raise a complaint regarding a washing machine purchased from your Gulberg branch on 4 August, and to request a resolution after two unsuccessful visits to the shop. The appliance, a Haier front loading model, functioned normally for around three weeks. It then began to stop mid cycle and display an error code, leaving the drum locked and full of water. This has now happened on every attempt to use it, and the machine has been unusable since 2 September. I returned to the branch on 5 September with the receipt and the warranty card. The assistant on duty informed me that the matter would be referred to a technician and that I would be contacted within three working days. No contact was made. When I visited again on 11 September, I was told that no record of my first visit existed and that I would need to begin the process once more. As the fault appeared well within the warranty period, I would ask that the machine be replaced rather than repaired, given that it has already failed once. If a replacement is not possible, I would accept a full refund. I would be grateful for a written response within seven days, after which I would have no option but to refer the matter to the consumer court. I enclose copies of the receipt and warranty card for your reference. Yours faithfully, Imran Sheikh
