bad service

I was to pay my account on the 31st of June,it was about 9-10 and the shop was still closed.later i go and want to pay my account and get some parfuum and sunglasses.I get my parfuum and go to get the sunglasses,i ask the cashiet to open so he said he will fetch the key.after 20minutes nothing happens so i go and ask he said he send someone to fetch a key,so i took my things and put it on the counter and walk out.Every time when i walk in Edgars you must help yourself ,if you want some bigger numbers you must walk to the cashier and he or she shout out to someone to help you,is that servise or what.I am n big lady who must take a big number and most of the time is there nothing,well big numbers but not vir older people so please do something about that branch.I go and pay my account now at Jetmart.I hope you can do something.Thank you
