Faulty product STILL has not been replaced!!!

I purchased a Dell monitor online from Incredible Connection on the 17 th of April 2019. My order was delivered on the 23rd of April 2019. Within days of using the monitor some pixelated lines appeared down the screen. On the 29th of April 2019 I contacted IC via the website to let them know of the fault and ask what the next step should be. I received no response. On the 30th of April 2019 I contacted IC via Facebook. I was told that the monitor could be collected and replaced OR I could go to the Somerset Mall store myself to get the monitor replaced - this would be quicker I was advised. I am not sure what date it was but I drove through to Somerset Mall store where a technician inspected it, said there was definitely a fault, and then advised that it was under Dell warranty and that I must rather contact Dell where in the next 2 to 3 days my monitor would be replaced. I then went through a very extensive process logging the fault only to be told that it would take 10 to 15 working days! I advised that I would be going back to IC. I contacted IC again on the 7th of May via Facebook and was advised that a collection had been booked for me. I have contacted IC on Facebook 3 times since and each time been told that they have forwarded the request. So in summary that is 4 times now that IC has failed to contact me. I was given incorrect information regarding getting the Dell to replace the monitor.
