Sef Payment Gap not Decreased

I have called discovery call centre three times day, each time I call the call is dropped. <br> There have been a few claims submitted but I do not see these being reduced off the self payment gap. <br> I have requested a detailed summury of claims, and need clarification with regards to certain claims. <br> <br> Clearly the staff are at the call centre do not care as each time the call is dropped if this is a technical error, I do not receive a call back.
