Unhappy and shocked customer

i am so dissappointed with the service i received from edgars in gateway , i went there around 5pm to buy clothes for a child and i paid using payjust now , had money deducted from my bank acc however not received in their side no slip came out , and i was told to come back later everything will be sorted out to get clothes and i finished work at 8pm and go back there, the cashier that was helping were no longer there with the supervisor i was asked to describe a supervisor and i couldnt then I was taken to reception where they found clothes , and told me to go and pay then i asked for what because i did pay ? They tried to get hold of the cashier i guess they couldnt and then come back to me saying they will need to send an email to payjust now and they do need my id copy , bank statement and a screenshot from payjust and that process will take 2 to 5 working days mind i went there to buy clothes for kids to wear on a Christmas day , then I told them i need clothes that is why i came to buy , a lady told me there is nothing they can do unless i pay for them , and time was around 8:30pm my transport had left me because of this , and I had to pay twice because i needed clothes and nobody was willing to help , And still there is this two outstanding installments in pay just now that i dont know what will happen with them plus my money that was taken out from my bank . i am so angry right now i trusted edgars in gateway and always buying some staff there never thought they can be this bad once i get my money back if I will i dont know i will never visit that store again !!
