Disgusting service !!!

I app**** for a store card/account in Dec 2017, I was told to email bank statements and shortly after got a call for more info, I was asked income and being a person who own my own company I gave my net not gross and was not asked either by the agent calling .. this then caused so many problems and my application was closed .. ackermans then told me it was not my affordability or credit but I was suppose to give them the gross income as they match it with bank statements (the person who called me for info did not mention how important it is to rather give the gross income as the system matches it to your bank statements .. so they sent it to relevant departments and asked me to reapply .. so I did immediately .. it's taken them 3 months to let me know that it can't be fixed on their side (IT / system issue) and I can try and reapply in 6 months ! I'm Disgusted at the pathetic service from Managers who don't call back and show no apologies in their tone of voice ! To name Anastasia, Cheslyn and a few others who I cannot remember as it's taken the whole world to help me ! I'm sure the shareholders would not be happy to know that people who want to spend their money there are being turned away! It's really such a pity because out of all the retailers I shopped around at when finding where to apply their clothes are the best value for money
