The escalations team is just as inefficient

I wrote to your team last week Wednesday about a rude call centre agent by the name of Tshego. I was promised by the complaints team that Jackie Rayden will get back to me within 5 working days. I have followed up both on twitter and on hello peter and you guys still haven't contacted me. I have now been advised by your call centre agent Tasnien that you have closed this case. So please tell me how you have closed it without 1 getting your agent to call me and apologise? 2 Jackie has not called either to follow up?
