Incorrect insured value captured by MiWay

I contacted MiWay a few weeks back to get a quote for my cellphone. I gave the consultant a value of R25000 for my P30 Pro and was gevin a premium of R97 a month which I accepted. Today when I received my updated policy scheduled I noticed that the device was actually insured for R2500 and not R25000. Immediately upon noticing the error from MiWay I contacted them again to state that the insured value is incorrect and should be rectified. To my shock and disbelief I was then told the the premium would be R955 instead of R97! Why should I pay for the mistake of a consultant who clearly captured incorrect details. You contracted me on a premium of R97 and I accepted it. I want a copy of the recording where was contracted into an agreement for my cellphone and if this is not rectified I will refer the matter to the ombudsman. This is strike two MiWay.
