Poor service delivery

In October last year, ideal prepaid had come out for installation. Absolutely negligent, crossed power between my unit and the above to me. I had spent twice the amount in just two weeks, only to find out, I had been paying for the above unit usage. The installers had come through, rectified, but have till date, 08/01/2026, not refunded me for the additional usage amount. The only response I have been recieving since before the festive period is that the refund is awaiting authorisation. Poor management response to urgency and accountability.
