DISSAPOINTING SERVICE FROM CHECKERS SIXTY60

Ive been using the Checkers Sixty60 app for the past year - Its quick, easy and convenient until my last order. On Sunday 6th November I placed an order for R700, the order was shopped and money debited to my account. Two hours later the order was cancelled and I was informed that there was a system glitch and the order had to be cancelled. These were items I needed urgently and was advised that I will receive App credit in order for me to place the order again. I was told "please check again in an hour or two"...it is now 8th November.. Im still checking. I have been calling everyday and am being told that "they are working on it but cannot give me a turn around time". So now I am out of pocket of R700 and just have to wait until my refund or credit is being processed. Ive spoken to at least 5 people at the customer centre and they are so friendly and yes they have no control over the system glitches... my issue is that I am told that "they understand my frustration".. but do they really? That R700 could very well be my last R700 I have left and have used it to get food items to feed my family... but I guess their "understanding" will feed my kids for the next few days.
