Horrible online buying service

I have received the worst service ever from CTM based on my online purchase I made on the 29th of November 2019. CTM promises to deliver nation wide and to date no one can tell me when I should expect delivery of the items purchased. I made follow ups couple of time to this date no email response and and in terms of telephone follow-up the sales expert promises to confirm delivery date but never feeds me back. Below is the details of the issues experienced.

Upon placing the order online on the 29th of Nov same day the sales expert gave me a call to say he will get me a qoutation for delivery costs.

On the 03 of Dec which is four days after online order, he gives me the qoute with delivery charge as the online system is unable to determine delivery cost. And he promised to get me the best delivery cost.

The delivery cost was R4200 to deliver to Kuruman from the kimberly branch. I then asked why didn't he try to get items delivered from vryburg branch as it is closer to Kuruman about 100km less than delivery from Kimberly. He then said he will try to find me options of similar tiles from Vryburg as they don't have the ones I want in Vryburg so I can pay less delivery cost. About three days passed without any feedback. I then decided to just pay for delivery cost from Kimberly. Post my payment I then called to find out when I can get items delivered whilst talking on the phone around last week he said he is gonna call Kimberly branch now and let me know and still today no feedback and I have made a payment in full.
