The worst service from Medscheme!!!!

Medscheme are sitting with a huge credit of my father. They are simply not refunding him! After months of excuses I have had it with them!! Now another Administrator has taken over the Hosmed administration and there is simply no word from Medscheme. Each email I receive from Medscheme reads the same. Apologies, will revert soonest. Months has passed in the interim and nothing gets done! Meanwhile I am financially responsible for the shortcomings of my parents!
