Poor Service. 18 days and still no internet

I have been assisting my father with installing a new LTE service through Webafrica. It has now been 3 weeks and he still does not have internet. The SIM card was damaged and we have been waiting more than 2 weeks to get this replaced. Every discussion with the Webafrica team is an apology but nobody can confirm whether the SIM card has been sent. Today is day 18 since contacting Webafrica and still no closer to a solution. Very frustrating. I requested to be put through to a Supervisor this week and was told that it is not policy to speak to a Supervisor..:
