Innovation failure

Dear Mr. Price please decide on what you want to do,recently you I produced scan to pay with an account because I am always on the road this came as very convenient and have been using that scan to pay for over a year and half ...Friday y I went to Mr Price Northgate failed to use the app was told it doesn't work any more as it was under maintenance which I understood and bought clothes with my bank card mind you I have credit on my account..I understood cause I needed the clothes for my children..Sunday the 5th I visited Cosmo mall as i was about to pay the same error message appeared after 30 to 45 minutes of sweet manager Nozipho assisting and failing I decided once more to use my bank card..I was furious and still am,why do I have an account if I have to struggle to use it?here are my demands either you reimburse me for my purchase and take from my account or you close my account ASAP and you refund your overpayment of R14,I am giving you 2 working days to resolve this..and to Nozipho thank you for the assistance,you are one of a kind.Mr Price make up your mind if you want us to go back and use cards
