OPTICON PBX SYSTEM

We have a 2 telephone lines with our Opticon PBX.<br> <br> Telephone numbers are *** and ***.<br> <br> This Opticon PBX system needs to be reprogramed , which I have opened a number of cases already with not one person coming back to me in 3 weeks - and I have decided to rather cancel this system.<br> Please cancel both telephone lines and arrange to uplift this system and cancel my subscription with Telkom.<br> <br> Please let me know what you require from me as a business owner to perform this action above.<br> <br> This system is not working and have been messed around long enough with you support center.<br> I can't have my business support and sales be affected by this PBX system due to you not offering support to your Telkom products.<br> <br> Please provide me with that info you require to make this process happen?<br>
