Unhappy about Superbalist

I bought Nike sneakers last month from Superbalist....they delivered them,but when I open the box they were not in good condition...they were eaten by Rats...and smelling so bad....I logged a return and the came to pick them up......and 2 days later they sent me an email saying...my return was no in a satisfactory condition...they actually were trying to say it's my fault where'as they delivered them in that condition.....I explained to them that the reason I returned them it's because I received them in tht condition I even sent them pictures of it.....then one of their consultant sent me an email saying they did investigation and I will receive my refund within 3 to 5 working days......nothing was in my account after 10 days....then I sent them email to please make a follow up on the issue....thts when they rep**** to say I must send my banking details.....I sent them banking details and they again promised to send my money within 3 to 5 working days.....it's over a week now...and still waiting......do I really have to beg them to return my money.....? They don't care about their customers....they only care about money coming in....
