Refunds or monies paid to service providers

When visiting a medical practice one can save a good percentage on amounts used by paying cash and claiming back from Discovery.<br> <br> HOWEVER<br> <br> Discovery seems to have no customer service priorities. This as they do not notify if there is a problem with the claim regarding other queries. This is just left aside until I the customer follow up as to why it is not paid. Further more they don't seem to see the urgency of the matter when they are advised that this is now needed and should be paid ASAP.<br> <br> I will not pay cash and claim back if I can avoid it as I am not sure that they would ever attend to the matter if I did not follow up myself.<br> <br> Maybe they see us as club members and don't see this as Business?
