Terrible customer service

I became a member in my personal capacity in February. I noticed my monthly account was not pulled off so i contacted discovery to find out the reason. They informed me that my employer has settled the bill. This not being correct i then requested them to change the details to ensure that the billing is for my personal account and not for my employer. They subsequently cancelled my membership while I was overseas and now when i am querying the matter, the call centre agents are either very rude and unhelpful or promise to call you back and never do. I am disappointed in the service and with the lack of regard shown to me. I have done all that I can to rectify the situation but clearly it seems that discovery does not value their customers
