Bad Service CTM Worcester

On 12 February 2020 I visit CTM Worcester and obtain a quotation for tiles, I gave the sales rep Terence my floor plan measures and he work out the amount of tiles I need and gave me the quote. I then went with my wife on the 9 February 2020 again to Ctm to confirm the tiles I want , Terence was not there and I was assit by a other sales rep Rumark, he notice that Terence didnot work out my measures correctly and correct it, the amount for all my tiles with correct measures done by Rumark was R12,896.20. I paid the amount by Terence a few days after and collect the tiles on 15 February. During the tiling process I discovered that my tiles isnt enough. I phone Rumark and explain to him my shortage he said Terence is not there, I then drove 60km to Worcester and stand for nearly two hours explaining, to the Manager of CTM Johan my story, we agreed that my quantity were not calculate correctly and that Ctm still owe me tiles I was given 18 boxes of which I was supposed to get 20 for one room and another 13 boxes where I was supposed to get 16 for a other room. The manager gave me petrol money of R400 and said on record that he will deliver all outstanding tiles on the following day, he explained that he must get tiles from another store because he doesnt have stock The sales rep must take full responsibility. Johan came with only 3 boxes of one room and not the other 2 boxes. He left without mentioning anything of the other 2 boxes. CTM Worcester Johan please give my 2 boxes of tiles you owe me as you did the measures and you work according my plan. There is expenses relating to your incompetence and negligence.
