Non-existent customer service

Wesbank's customer service is non existent and they are one of the worst experiences that I have had with regards to service. I asked to make an payment arrangement and they deducted the amount anyways after they confirmed that they would not do so. I had to pay more than R100 in airtime to rectify the mistake that they have had trying to get a hold of a representative that nobody seems to know. Shockingly bad, this will be the last time that I use Wesbank for financing
