Worst service ever!

I have had troubles with them from the start and was hesitant, but gave them the benefit of the doubt. After eventually receiving my machine things went well, however I recently cancelled my contract and was contacted to confirm the reason for cancellation etc. After they accepted my reason they informed me that they have a 30 day cancellation policy with which I had no problem and they would come and pick up my machine on 31 August. I requested that they come and pick it up earlier as I still had 2 empty bottles that needed to be credited to my account. I received an answer that they could not pick it up before 31 August due to the 30 day cancellation policy. After the machine and bottles were picked up, I was billed and the 2 bottles was not credited. I sent an email and received a response that it was escalated to management. I heard nothing for days and after following up once again I received an email last week Friday on 8/09/2023 stating my account was credited and they needed my banking details to do the refund. I immediately rep**** with my details and still have not heard anything from them. No feedback whether my email was received or when the refund will be processed and paid. Aquazania needs to train their staff in customer service! They deliver the worst service ever!
