Discovery's lack of communication with clients

I've been sending emails to discovery regarding my medical downgrade and no one seems to care to get back to me or even communicate after i've sent the form back to them, they just refer to the WhatsApp which does not give me the solution im looking for. the last mail came from Lindo Mcunu and i responded back to ask Lindo to call back. its been two months now. Get this lindo person to call me back so we can sort out my plan.
