Urgent refund required

Our switch over from ADSL to Fibre was a terrible experience. Eventually, after many days of frustration it was sorted out around the 28th of February. We signed up for the R799 uncapped deal which promised a 12 month contract with modem (R1300), connection fee (R999) and installation fee (R1710) included. This past week we received our first invoice from Telkom after the switch over, only to find that they charged us for the connection fee and the installation fee. You can imagine our shock at receiving an invoice to the value of R4243.17 (incl. VAT)!! Please confirm that you will credit the amount of R2376.32 plus the associated VAT to our account before the 9th of April when the account is due for payment.
