Layby cancelation Terms and condition on the till slip and website where the same but the cashier had their own

The customer service I have receiving over this past months Ackerman Protea Glen mall, firstly it started when I layby a few winter items when my baby was 6 weeks old in April 2019, but then those same clothes I had layby I got as gifts from friends and family so I wanted to cancel my layby so I can change the clothes, I stated that to the cashier then she told me I can't cancel I had to wait till my laybe expired I didnt understand as the till slip said otherwise and so did the website so I didn't urgue and asked her if I could do another laybe or add on then she said I could do another, I waited till first layby expired hoping to take the cash and add to the second one to my surprise I was told that I had to wait 15 more days for it to be out of the system, I then wrote to Ackerman on their website to find out about these terms and on the 1 August I got an apology and my complain was then forwarded to the Divisional Manager who they said will contact me in 3 working days but he only called on the 28 August at 11:10, then I told him that I did go back to the shop since I waited on him for days and when I got to the store I spoke to the manager stated my case and he then told me that if I cancel my layby I will be blacklisted to not laybe again for 6 months, even after telling him why I am canceling so I got my voucher and used it as I was shopping on the very same day. The Divisional Manager guy I spoke to now told me there is no such thing I can laybe at any time I want to. I have been going to Ackerman to shop for my baby even after this whole drama but off recent I decided to go layby I was still told that since I am blacklisted for canceling a layby I couldn't before I could even say to them I was coming to laybe, I immediately walkout the shop and honestly don't see myself going back to that store ever again. I really and honestly don't see why and how they would hold a grudge and give terrible customer service over a petty thing like that. I love the clothes from Ackerman for my daughter but all this is really not worth it. Reason I wrote today was cause I wanted to get my dates right as I had to check on when all this happend.
