Frustrated soon to be ex-customer.

I have been trying to cancel this 'service' for two days. I only get automated replies and there is no option to speak to a person. The app only hangs and the WhatsApp platform has no option to cancel. I have sent e-mails, received reference numbers and an automated response that promised me that I will be contacted withing 8 work hours. Nothing after that. I have a credit balance, but still they put through a debit order every month. Shocking service!
