Appalling Customer Service!!!

What an absolute disappointment dealing with Sell Direct! I was offered 2 contacts via Telkom. The sales agent was great I even mailed there department to credit the amazing customer service he provided. I called them back on the 1st day the phones arrived to check and confirm the details of the contracts and to my surprise they never activated insurance as requested. Since then it's been back and forth calling them to add insurance, I'm currently being sent from pillar to post between them (Sell Direct), Telkom insurance and so many other insurance companies the list goes on. According to them Insurance was meant to be added with the inception of the contract and now cannot be allocated to the accounts. It is absolutely ludicrous that they claim to not have a contingency in place to get insurance added. As per Telkom ts and cs insurance ought to be added within 7 days of the contract. It is day 8 today! Surely I cannot be penalized for incompetence on there side with the advisors failure to add Insurance!? I have been speaking to them every day for hours trying to get this sorted with no joy!. There agents are so rude and unprofessional. They drop the line as soon as I start explaining, having to call back wait in a q only for the same to happen. Those that has been dealing with my issue makes promises that nobody keeps. I have escalated the issue to the managers but never received any called backs! I'm fed up and exhausted at this stage. I have lost complete faith in this company!
