Bad service with old mutul call centre

I sent a money to my sister via send money ; got the code only happened that i forget the pin. I called several times to cancell but i always the phone got cut when iam about to finish. I spent R40 airtime but no help. Whatsup card division; they tried to help by taking my number; sent to money account division; instead the call centre agent just missed call me intensional from ***. This is so un professional; every time when i called there is no help. Old mutual need to pull out their socks; especially with banking sector; there are so many banks that can provide better service to ud and also be efficient when we need help
