Failure to get Response from The Platinum Group

on the 10 July 2015 I bought a mans shirt light blue at one of the vertigo store in Brooklyn store in Pretoria. on the 13 July 2015 I returned the shirt because it didn't fit (and left it at the store), I was promised another size that will be collected from another store.<br> To date i haven't received a call from the store as promised, and it has came to my attention that the store is not operational anymore. <br> I have sent emails and made calls to the Platinum Group and they keep on promising me that the manager from a menlyn store will contact me for an exchange till today no response. Either I am being taken for a ride or made a fool. I think I need my refund. I have followed all the right process to deal with this matter but now am getting agitated, because am the one who keeps on making follow ups and none whatsoever is taken from the Platinum Group. Please someone needs to take Responsibility and deal with this matter.
