Mix Telematics Reporting False Information, Simon Shiba being useless and sleeping on the job.

This company is not to be trusted at all. I have a tracking unit with them which has a running debit order on my account. every month without fail, they debit my account but last month they report that I had missed a payment when the debit order went through. this affected my credit score on ITC and I raised the matter with them via Simon Shiba their Consumer Snr Credit controller consumer. This Simon guy has been nothing but useless....and I mean completely useless. he never provides any feedback. the matter was raised on 31 March 2021, today it is 26 April but the matter has not been resolved and he has never provided an feedback what so ever...they call him a senior controller but there is nothing senior about his performance....the guy behaves like an intern. I need this matter to be sorted out ASAP because is it negatively affecting my credit profile.
