Customer Services do not rectify the issue

Customer service is pathetic. Since mid October 2022 till now my husband has been trying to get them to reverse erroneous depletion of his doctor’s visits. My visit visit to the same doctor were withdrawn from his profile and subsequently his visits could not be paid by them - even though he had many that should be available. Countless emails had been exchanged and promises to rectify it had been broken over and over again. He got 8 different follow-up reference numbers but the problem is still not sorted.
