Review CTM false advertising, and very dishonest and poor service

Multiple issues: 1. They advertised tiles at R 79/m^2 and when I go all the way to the PE shop a far distance to get them, they are also advertised on the walls, but they have no stock of it on the site. The next cheapest tile in stock is R100/m^2, a huge difference for a very poor person to afford. I paid in cash and left note left for manager that difference between the 2 prices must be credited to my account or refunded due to the false advertising.
3. The tiles were promised to be delivered the Friday and only arrived the next week Tuesday after numerous calls I made to hurry them on, while work at the site remained stalled.
3. The agent miscalculated the number of tiles and adhesives in the order.
4. I reported and left many messages for CTM on various social media and emails to contact me back or refer me to a higher platform that can resolve the issue. They ignored me.
5. Manager at PE shop contacted me eventually and brought more tiles at R79/m^2 in exchange for the unused R100/m^2 ones and promised to refund me the difference into my account. New tiles had a few cracked and broken ones in the packets and I was told the builders can bring them in and exchange them. Upon arrival, they were told I only had R 200 credit as opposed to R 2000 as promised and still could not complete the job. I left a follow up message with the manager who never replied.
I would advise people busy on big projects to not trust this company as they are dishonest and love wasting time, changing stories, and stealing money.
