Inconsistent Electricity Charges (Capitec app)

The number of units we get is extremely inconsistent and we need an explanation as to why this occurs with proof. If the system is at fault, a reimbur*****t of units would be appreciated. I have attached proof of my claims toward the above.

Your consultants are refusing to furnish me with contact details for the third party that deals with this. You will have to resolve this issue as the middle man.
