I’m Beyond Words. The Worst Service Ever. Can’t Find The Right Word To Describe The Service

I’m Beyond Words. The Worst Service Ever. Can’t Find The Right Word To Describe The Service. I have been having endless problems with Cell C. The account was paid late and have received their voice automated calls every half an hour. I sent the proof of payment on Wednesday 03.07.2018 to their email address ********** but still the half hourly calls didnt stop.

My sister who is the account holder eventually called them and the lady said the payment is not yet reflecting, but she can she my email in their system or something. Yesterday 05.07.2016 my phone was suspended, because according to WHOEVER saw my email, didnt allocate the payment and it takes them or their system 48 HOURS TO UPDATE!!!!!!!!!!!!

What type of service is this, that the buck gets passed until their system updates payments, why could this not have been attended to when the email was received on 04.07.2018 at 10h55 when i received the auto response or when the account holder called through.
