Life inconvenience, Money back Plea

My name is Nthabiseng, I went to Pick n Pay Evaton, bought groceries and asked for a cash back of R2500, the lady that was assisting mW by the name of Nthabiseng till 2 told me her system went offline, when I check on my app the R2500 was deducted, she said I must wait 5 minutes it will be back into my account, I waited 10 mins, then team leader by the name of Ipeleng told me to go home she will call me to check if I got the money, no call, This morning (Monday) I called Capitec and was advised the money is on pending and can be fixed by Pick n pay, I called their call centre, spoke to a helpful Melisa and was given ref *** and transferred me to the branch only to find their landline is not working, I a called the call centre AGAIN spoke to a manager who said they are aware of the problem and he gave me a cell phone number to call with my airtime said it is the manager's number, the number did not go through, called AGAIN spoke to Wendy who transferred me to Allison the manager, who advised he will call the store and get them to call me, Eventually Ipeleng called me and told me they can only escalate tomorrow as this happened on a weekend, Sadly I used my airtime of R250 for all these calls and had to make an excuse for my Son's transport...Now I have to wait until I don't know when. Honestly this is a lot of Money
