Consumer Redressal

The complain is regarding the company named Xiomi.. bought the company's power bank back in November last year it had an 6 months warranty.. lately back in January it started giving problems I raised a complain for the same on the 31st of jan n was said that a replacement will be made as these power banks are not repairable.. n till today I haven't got any update either through a message, or a call or through email regarding the replacement. Have called them almost 30 times now whenever I call they put the call on hold for 10 mins or so n nothing to do I hv to disconnect. they have even told me to not use the powerbank.. so I'm not using it since January after all wats the use of buying a power bank if u can't use it.
