POOR SERVICE MUST FALL IN BRITS MALL STORE

Yesterday i went to edgars brits mall in brits and their service was terrible and would like visit that store again or advise any of my family members to. Like any customer my expectations was never met.... i app**** for an online and their ***** dept contacted me on saturday for confirmation of my application and told that will get the outcome via sms(approved/declined). On monday which is yesterday i received an sms saying my account application is approved and all i need to do is to bring my ID and SMS i received to any edgars store in other to get a card, being happy as i was i went to brits mall store . Their customer service lady told me that i needed to bring in my ID , PAYSLIPS AND 3MONTHS BANK STATEMENTS in order for them to confirm my application and they even called a lady by the name of NHLANHLA who said they not going to help me. My question is why did i receive the sms saying what i need to bring and to be told that i cannot be assisted in the first place? The other thing is the service i received from that store is pathetic and also think that the staff needs training on customer service......... PLEASE HELP
