Remi Group — Complaint regarding service of my fan

For 2 weeks ago I got my fan malfunctioned. I contacted the branch from which I purchased it they told that a person will contact you within 2 days. After one week I called them again and asked for the that's guys number that to I have to call them 3-4 times until they respond to it. Very bad about it. When I contacted that guy he asked for the complaint id and warranty I have the details and he told will come in two days and that part they don't have it. After one week I called today still is complaining that the company has not yet delivered it to him and will take another two days. I really don't know is it the reputed company's mismanagement or careless to its customers or is it the person delaying it. Please resolve the issue. Will be attaching the complaint id for your reference
