Bad service

What services On the 20 December 2021 I did a laybye at sleep master president hyper and the service I got was not good but I was understanding because the person helping me was in training and everybody have to get trained in some way. 22 Jan 2022 I went and paid off my bed and was told because it's not a full bed set only buying a mattress it's a special order it will take 3 weeks before it will be delivered I was OK and understanding again and 4 weeks later I couldn't go to the shop coz I was a new mommy with a newborn baby I called to find out about delivery and the details of my mattress I was given a whatsapp number to give them my invoice number so they they would find out what's happening but was told that the wrong mattress was delivered and they will order a bed this was on the 27 February 2022 and again I was patient. On the 10 March 2022 I took myself again to the shop to find out what is happening with the mattress was told again will have to wait for it coz they only put in an order the Friday before meaning they put in an order on the 3 March 2022 and the mattress will arrive on the 22 March 2022 and it's past that date and I again as the client must call or take myself to the shop again to find out what is happening. What kind of service is this that one should get for a mattress that is fully paid for and as a client must keep asking instead of the shop keeping me informed of what's happening?
