Appalling Service

I am absolutely appalled by the service from Nimble group, I previously wrote a review and received only 1 email back stating the matter will be looked into and that they have attempted to call me, I responded back asking for all calls, emails, and WhatsApp chats to be reviewed as I do not want to receive any calls from the company, I'm also unable to answer calls due to work. I have not received even an acknowledgement email back or any type of response, I also reached out on WhatsApp and spoke to Kelly Anne, who asked me to send her all of my documents to process a refund on the debit that was processed on the incorrect date and a new payment arrangement was then set up, I requested for the debit order to be cancelled/stopped however it still shows active on my banking app this is over a week now, after sending my documents for the refund I have not had any communication from Nimble group, when contacting them on WhatsApp everything needs to be explained all over again. This is time consuming and the service from this company is absolutely terrible.
