Unhappy customer

Good morning. Last week Friday I received my new phone and router from Mondo. As per their regulations I waited my 48 hours for both simcards to be activated and I've send emails, phoned and even chat on whatsapp to activate my simcards. They communicated via whatsapp late yeaterday afternoon that I should remove the new simcard from my phone for an hour and put it in again which I did but still no access on both simcards. This is really poor service from them and I expected an agent to atleast call me back within this time frame whichnever happened. I jave reference no KA4NBJ but it seems like they dont even bother to do follow ups. This is my 2nd contract with them but I never received such bad service.
