[Resolved]  Ava Merchandising — bluetooth speaker not working if removed from charge

Address:

400708

I bought a bluetooth speaker in delhi airport. It worked fine for a few days. But now, it works only when it is put on charge and stops when removed from charge. The battery may have been drained out i believe. This speakers also make a shrill sound when just plugged in. The speakers are required to be replaced. The bill number is 00000va[protected] for reference. Please let me know, how is it to be replaced.
