Pathetic service from ASAP

Hi, I placed an order via ASAP yesterday(22/04/23) only to receive part of it. I have since contacted them several times and was told it's been investigated by the refunds department who will communicate with me via email. I got an email just before 5pm saying it's been escalated. However during this time I had to spend more money to purchase part of the missing items as I was expecting guests. I called in twice today and the 1st consultant told me he will refund me or send me the missing items along with vouchers. The 2nd said that the 1st was unavailable and she will assist me and will forward everything to the refunds department. Here I am waiting feedback so I called again only to be told that the refunds department will only be operational tomorrow (Monday). It's not the 1st time I had items missing but due to it being 1 or 2 I was credited. I'm so frustrated at the service especially that staff consulting lack of knowledge with regards to their refunds department being closed today. I could have made alternative plans to get the basic things that I require.
