Not happy

Was in Canal Walk branch asking for credit upgrade on my store card , was assisted by a very helpful lady. She gave me a reference nr. She told me a upgraded card with extra credit will b issued to me and that they will phone me. Got sms the Monday to confirm they will call back . After a week went to KC branch. Sat their for 45 minutes missing an appointment. They could not figure out how to help me after they spoke to someone on the phone. Telling me the so called big branches don't sometimes know what they doing.and promises customers then they must sort it out. Long story short it's been almost 3 weeks no call back...I'm just dumbstruck because I know of your standards where suppliers is concern, your audits @ companies etc. I don't earn much but I'm paying my account on time..wake up guys we need to add to the economy. Thanks
