Amravati, Maharashtra, 444601

Store closing time of Amravati (Maharashtra) on Saturday is 3:30 PM but when I reached to store at 3:05 PM then they told me that " he closed their servers i.e. he sign out his profile " . Therefore I couldn't purchase my products ...
Also there is miss behavior with my mother, when my my mother asked to employee that we are only 5 minute late then can you please do me my shopping then they refused me ...
