Poor customer service and failure to resolve a billing dispute

I am disappointed with the way my billing query has been handled by Xtraspace Storage Robertsham. I had an outstanding rental amount, which I acknowledged and paid. I also paid the administration fee of R308 as provided for in my signed rental agreement. However, Xtraspace subsequently charged an additional R42, which I specifically disputed and repeatedly requested them to explain.

Despite my written correspondence, Xtraspace has failed to provide a clear contractual explanation or supporting documentation for the additional R42. Instead, I continue receiving statements/invoices as though no query was raised, without addressing the actual dispute.

I have acted in good faith, paid the amounts I acknowledge as due, and communicated my concerns clearly. I expected Xtraspace to investigate and respond to the specific billing dispute rather than simply continue sending statements.

This is extremely frustrating and reflects poor customer service and a failure to properly resolve a legitimate customer query. I am requesting that Xtraspace: Address my R42 dispute directly; Provide the contractual basis for the additional charge; and Correct my account if the charge cannot be substantiated. I would still prefer to resolve this directly with Xtraspace, but I am escalating this complaint because my repeated requests have not received a substantive response.
