Poor Service Delivery

On the 12th June 2020 we moved out of our flat a week later I asked documents from Impact Meter Services to discontinue the electricity (Account Number 403895) telling them that we moved out on the 12th June 2020. After receiving the relevant documents, all the relevant parties' details were provided (ID copies, copy of bank account into which the refund has to be deposited). On the 27th August 2020 (Ticket number 113480) I received an email from Lindiwe where she asks ".. Precious, please ask client on batch for refund. Disc 89431). Both Lindiwe and Dudu sent me an email saying "...finalised and processed'. After at least 10 different ticket numbers (speaking to Dudu and Lindiwe) today, 22 September 2020, after asking Dudu if there is any movement in this case, Lindiwe answered asking once again for all the relevant documentation as if nothing has ever been sent to them. It has been 12 weeks, and Impact Meters states that refunds take 4-6 weeks. This is totally unacceptable and the worst client service I have ever encountered.
