Sad SADV Service!

I am on the uncapped data package with SADV. At the end of November 2018 i was incorrectly double debited. Then on the 10 Dec 2018 my services were switched off for the reason given "Account overdue". After long discussions they realized their fault and reinstated my services with the promise of a refund. I did not get the refund and at the end of Dec i was debited again. No one could assist me, not even the manager Mandla Mhlungu and was told to wait for Riette Facondini to return from leave in January to resolve. I tried contacting the CEO Shaun Barkhuizen, but was refused access to his contact details but was told to email ********** and to date no response. I received a call from Riette on the 04 Jan 2019 apologizing for the inconvenience and promised to refund me immediately with interest which will go through on the 10 Jan 2019. Guess what.... no refund to date 23 Jan 2019. The incompetence is shocking! I caution you, the public from getting into business with SADV(South African Digital Villages). Their technical support has been fantastic but their accounts system , personnel and management are just plain down ***********. I need my money refunded with interest immediately. I need confirmation in writing that my account is up to date and that your billing system problem has been resolved. I need my compensation as discussed for the lost services i paid for and my inconvenience and expenses for your incompetence, which btw, i was offered compensation of which i accepted but it was later withdrawn by Mandla who asked that i prove the inconvenience suffered first.
