Double debiting customers

Hi,I have been using LiquidCapital for the past years since I purchased my car in 2017 and I have never had a problem when it came to renewing my service plan after certain services that had taken place,a consultant would call me and we renew over the phone and there would be no such thing as double debiting me.Last year around September/October I was called and asked if I wanted to continue and renew my service plan with liquid capital,and I gladly accepted because I have been with them for years and never encountered any problems or challenges,now all of the sudden I renewed my service plan with them last year only to find that they are double debiting me ,they debited the new amount on the new extension that I agreed on which was R453 and debited me the old service plan amount I had with them which was R564..,Now how the hell does a business do that especially when I have been their "loyal customer" for the past years and when I called and spoke to Kamogelo he tells me it's not the consultants job to do the cancellation but that time I'm renewing my extension and it was never mentioned to me that I need to do a cancellation with another department,all these years that I have spoken to consultants I was never double debited till only now.

This is damn right nonsence because your level of incompetency is now at my expense and I have to suffer for it,I don't wana associate myself with your business anymore and wish to take other plans that put customers first and are clear on what is expected because the level of service is appalling ...imagine the amount of money you have been taking from me freely with no service rendered..R564x4 =R2256,I have been trying to reverse those amounts because this money you're taking is my children's money,you think money is just lying around for you to just take.Im really Disappointed in the service and your consultants don't even sound bothered or even remorseful for that matter.😡😡😡😡😡😡😡😡
