Maxx Mobile — portable power bank not working

Address:

Kozhikode, Kerala

i bought a portable power bank by Maxx from an online retailer. But it Has stopped working from day one. The charger gets charged up when I plug it in. But when i charge my phone using it it goes dead after a couple of minutes. I had relied on this for my travels and felt cheated when I got my battery drained and not able to charge while I travel. I called the service hotline and it never answers. I have it for servicing at the authorised service centre and even they can't help, they day that the company I'd not responding to their queries. They also said that a lot of people have the same problem and are not getting the product replaced or repaired by the company. This is a case of violation of basic rights to a customer. Please take action on this.
