VERIMARK CASSEROLE DISH

I had one of the first , 3 Litre casserole pans and took it into VERIMARK at the Mall of the South on 29/12/2019 for recoating. I have contacted THOMBINKOSI there several times and he promises to get back to me, and then I hear nothing. The last time I contacted him, was Friday 5th June. Again he has promised to find out what has happened to my dish, and guess what.............no response from him again. I can't tell you how disappointed I am. This is very poor on VERIMARK. Can something be done about this.
