Shocking bad service

I paid my subscription on Tuesday 20 August and was told that my service would automatically be activated. By the 21st it still was not. I logged a call to the help desk and was told 2 to 20 hours it would be sorted. When I called on Saturday to find out why it was not sorted yet, the consultant dropped the call after 13 minutes. I gave a 0 review, but still nothing. I called again on Monday at midday and spoke to a supervisor who said everything would be sorted by 3 pm at the latest. When I called back after 4 pm, I was told that nothing was captured from my earlier call. I went through to another supervisor who advised me to email the manager which a duly did. 1pm still no response. My reference number is seq***
