Helpful but not helping!!!

Accounts department has been really shocking. When contacting Lancet to sort out outstanding accounts was informed that they would re-submit the accounts using correct details and see if they would then be covered by medical aid. Was told that the account would be put on hold until then and they would provide feedback as to whether medical aid covered the costs. They then proceeded to hand over the account to debt collectors the very same week. Have phoned them twice since and both times the call centre agent was very apologetic and said they would sort it out. AND I'M STILL GETTING COUNTLESS CALLS AND SMS'S FROM THE DEBT COLLECTORS!!!! I am sick and tired of dealing with this account and will just have to pay to hefty bill out of pocket because of this useless service!
