As anyone had problems with singing up to smarty social tariff

I have similar issue with request to change to social taruiff
nce JUNE 2024 I contacted that link about social tariff there is no answer directly ZIP nothing, not even a NO! I have today here 2 records of the refernce Do you think I have much time on my hand to click on link, and complain about no reply?
Each time I contact live chat they explain there is someting not match in my details kept in the DWP portal,but they can not give screenshot as proof.
