Poor customer service.

I sent money to their account on the 30th of June by mistake, I even sent the proof of payment to their account office which the assured me that my money will reflect into my account within 24 hours but uptill now I have not received the money, I try reaching out to them but they don't even answer the call. This company has to do something about their poor customer care and also poor accounts assistant. Pls everyone should be careful when dealing with them.
