Bad service

I bought a geyser online on the 27th Jan 2023. I used the click and collect service. I received an email with my order number. The website says the click & collect service takes 2 hours for the product to be ready, 1st mistake I made was expecting an email notifying me that the product is ready for collection, no email received. I later call the store requesting a quote for delivery seeing that I won’t be able to collect. I am still waiting for the email……… On Sunday 29th Jan I decided to fetch as no quote has been received. I collected the item. Monday when the plumber was about to install the geyser we find out there are missing parts, I call the store to notify them. The lady is not sure and asked to call me back to find out. She calls me back a few hours later to say that the wrong geyser was given to me and new one will be delivered the next day (Tuesday). No apologies, no communication until I decide to call on Thursday. I’m angry at this point as there has been no communication with regards to my delivery. I have been inconvenienced for 3 days now as the old geyser has been removed. A lady answers the phone and asks me to hold while she looks for the manager to find out what is happening 5 mins holding they say the person is on lunch but will be back soon & requests to call me after 10 minutes. 2 hours later I get a call that my geyser was supposed to be delivered on Tuesday but they don’t know what happened. The geyser will be delivered tomorrow. I tell the lady that I’m really tired of chasing them around it’s been a week and I have not received any communication or even an apology from them. I tell her I want the geyser delivered today ( Thursday) and put the phone down. I have have still not received any communication. I’m really angry and inconvenienced by all of this. It’s the 3rd Feb and have not received any response from them.
