DSTV Help desk is not for older people !!!

DSTV not even deserves 1 Star. My husband is 77 years old and his DSTV Decoder insurance was in arrears. We tried to get an invoice for a payment upfront for 12 month. After 2 weeks and 20 emails back and forth they are not able to do that. Not to mention if they send you an invoice for 1 month they send always from a no-reply address that you cant get hold of them. They send not working payment links, asking to delete your caches etc. but they are able to send every day the payment reminder for the insurance. Is that Customer Service to not help!!!!!!!!!!!!!!!!!!!!!!!!!!
