Shocking accounts dept

Herotel Breedenet sent us a statement on the 17th March that we owe R 3,630.43, however there is no credit for the amount of R3 563.93 that we paid on the 11th Dec 2020. We queried this on the 19th March and again on the 26th March asking for a full statement and a copy of the invoice for this amount that they claim is outstanding. As we have a debit order account this amount cannot be for our monthly fees. Phoning the company results in listening to music for long stretches of a time and finally leaving a message with the receptionist has also produced no reply. Instead we are bombarded with auto-messages threatening to cut us off if we don't pay by month end. We have now settled this account to avoid cut off at a critical time of our 3 connections but are not impressed and no doubt will wait in vain for any response or a copy of the invoice detailing what this amount is supposed to be for. This all on top of a month of sporadic internet connection is just pathetic.
