Disgusting Customer Service and Poor service

I have canceled my Policy twice before with One Plan Pet Insurance due to them messing up my payments every single time. I now took a plan out with them again and app**** Online, where I qualified for a discount. This was end of August. I was then told that an amount of R285 would be debited from my account on the 1st of September, however when they debited, once again they messed up the amount as previous times and debited my bank account with R566.51. I notified One Plan the next day and have been told that my matter was escalated and that my refund will be paid to me on Tuesday the 12th of September. I have now followed up again, after spending all my airtime last week on them and all I am told is that I will have to wait until next week Wednesday the 20th. This was communicated via their WhatsApp customer service which they advised that they have escalated and handled it as if it is the first time escalating this issue for me. No urgency! When I emailed the sales consultant to escalate, he came back with feedback and advised that the Refunds Managers advised that I would have to wait until Thursday the 21st as they had system issues. I keep on getting different stories and feedback from One Plan. Their customer service is very poor, and One Plan has no care about their customers once they have you signed up with them. This is surely NOT Treating their customers fairly and is a huge Service failure. I am on the verge of cancelling now for a 3rd time and if I do, will never return to One Plan again. They are losing valuable customers by people who work for them and who do not care about their customers or the after-service. There always are issues with payments. Either they debit too much, or they don't debit and cancel your policy without your knowledge. Then the refunds are not paid as promised. The customer then needs to call after them to try and get it all sorted, just for it to all happen again in the coming months. This is really sad, cause One Plan is a good Pet Insurance, but their Customer service and or aftercare service for their customers are letting them down. I want my refund as promised I would have received it this past Tuesday already, TODAY!
