Bad service and *********** consultants

I am so tired of dealing with *********** people. I am constantly asked to submit the same documents over and over. I only want to claim back for a Covid PCR test done, these documents have been sent to Devlin du Buys twice already and I am still not getting anywhere. Every time I ask to speak to a manger, I am just told by a different consultant to submit the documents AGAIN. So tired of bad service!
