Unable to resolve refund request

<p>I relocated from my home in Alberton to a townhouse in Radiokop, Roodepoort on 1/08/2015 and Telkom transferred my phone service on 3/08/2015 as previously arranged - great service! When reciving my monthly account thereafter I was charged for4 jacks. although only one was inststalled. I had 3 jacks at my previous (large) home so I guess this is where the problem started - 3+1=4! After repeated monthly calls to Telkom call centre, I was finally requested to complete a "Customer Request" form and email it. I did so on 3/.6/2016 and now I get calls responding and promising to sort out with their Billing Dept.</p> <p>I am a pensioner and the extra jack charge adds R48.87 to my monthly account so now the total overcharge amounts to R684.18 and despite monthly follow up calls I have not received a refund, nor do I get the promised SMS with a reference number. Contact details for Telkom area management are non-existant, so how do I resolve this?</p>
