R40 cost them a customer

Cutting your wifi off because you paid the old amount and short paid with R40 due to the increased monthly subscription payment and your payment is on a schedule. No message as a reminder, no push notification on their app just cut off. R40 cost them a customer. Phoning their call centre you are kept in a queue for 20min when it’s your turn they say the operator is no longer available. After 3rd time I gave up. They start off with all bells and whistles to bad no follow through.
