Frontline don't care about the old good customers.

I have bought 6 x boxes off Active care pull up nappies from the Edenvale branch, unfortunately 2 off my customers died and only need large not medium. I asked on whatsapp if I could exchange 2 boxes and pay extra and they said yes I must have a slip (which I found) last week the 25th of August 2022 I took two boxes back. The one staff member said yes leave it at the front desk and I had to go and get the rite size. Which the staff in that department was on lunch and I had to pull a very big ladder to the right place only to dind different sizes but no Large. So I went back and asked if they can let me know when they have stock. I was ask to remind them which I did today. They said they don't have atock yet so I ask if they can assist in refunding some so that I can get the right size for my poor old client that really needs the large size. Just to get a phone call asking what is my problem. They can exchange but not refund. So I explained again. So that the manager Emtieeus could understand my problem. But he started getting upset and rude just saying that he is not willing to even exchange them if the do get stock. Because it has been 2 months. Who uses 6 boxes off 8 packets off 10 nappies in less then 2 months? And deal with the 2 funerals so that we can exchange 2 closed boxes of nappies (16 packets) soon enough. Because they don't want to assist old people not to embarrass them selves in wetting themselfs. Very SAD AND BAD SERVICE
