Shocking service & OWE ME A LOT OF MONEY.

I opened an account for an ISDN service and paid R3000 deposit in 2003. Due to consistently unreliable service an the inability of their technicians to resolve the daily breakdowns, I terminated the service on 29 Oct 2021. On 16 Nov 2021 i paid my final account in full. On 10 Dec 2021 I requested my deposit be returned to me and forwarded numerous and all the documents requested. After a multitude of calls and another series of E-Mails to their Credit Management departments and numerous undertakings from personnel at these departments, I am still waiting for the R3000 owed to me. We now cannot contact them at all!
