Still No Refund After a Month

I have been waiting for a refund from Ideal Prepaid for over a month after buying electricity for the wrong meter number. I reported it immediately and was told the refund would be processed by the 15th of June. That did not happen.I was then told it would be done by the end of the month. It is now the 2nd of July and I still have not received any update or refund. Every time I follow up I get the same excuse that the tenant or building manager can’t be reached. I have been patient and have done everything asked of me. At this point it feels like I am being ignored and stalled. I just want my refund to be processed. This kind of service is unacceptable.
