Appalling service

I was approved for a new application online on 27/11/2020 and to date Vodacom have not contacted me with an update. I was given an email address to follow up, received confirmation of my query, a few days later it was resolved, yet no one contacted me. I had to phone, only to be told that I had the incorrect email address. Whoever "resolved" my query did not have the initiative to direct my query to the correct email address or advise me of the correct. The poor level of service I have received is pathetic.
