Pathetic after sales service

I called old mutual call centre as I had an enquiry on my greenlight policy regarding the debit payment. Day 1 I waited for over an hour on the line just for it to be answered. Day 2 I called again and was given the assurance that I will be called from the relevant department. No one called. I even lodged a complaint via their social media platforms and nobody called me. I even sent a call me back about 5 times and no one called. Old mutual are quick to sell you their products but the after sales service is pathetic. I'm so sorry to be associated with them, never again. Seems like the agents are either sleeping on duty and always having a party.
