Service Plan Policy

I signed up with Liquid Capital early 2019 for my service plan. I was on a four months waiting period before they can cover my service plan, which was understandable. I signed up for 3 service plans. They didn't debit me in March so I called in to find out why they did not debit only to be told that my policy has been cancelled due to non Payment in March and this was done without my knowledge. I spoke to Sidney Manyoni who tells me that they sent me an sms to state that my policy has been cancelled, how can they do that without calling or even sending an email to state that the policy has been cancelled and how does a policy get cancelled due to one non payment. Now I'm being told I didn't pay in November and I didn't pay again in March but they debited me for December and January. They telling me they cancelled my policy due to not paying in March but why didn't they cancel due to the non payment in November but they still continued to take my money for December And January?? I just don't understand how the workers can be so *********** and not have any product knowledge. My car is due for a service and now I have to pay for it from my own pocket whilst Ive been paying my monthly premiums for three services. They are so useless and they are just ******** people.
