Neotel responsed on April 14 to say the matter will be investigated and feedback will be supp**** to me. Until today I have not heard anything from Neotel and have not received any communication regarding my incorrect bill. I will not pay for a service that I was told will be free!! I need feedback regarding my account and have it sorted out. Neotel's reply on HelloPeter: Hello H de Clercq, Thank you for getting in touch. We have checked with our team and your query has been assigned to a team member who will/has made communication with MyNet. We are sorry for the delay but this issue will need to be investigated full My issue as posted on HelloPeter: Was billed for phone that was told will be free Hendri from MyNet approach me without any queries from my side and said he can upgrade both my practices' Neotel phones to desksets that will cost me absolutely nothing. After I met with him, I agreed to do the upgrade at no cost. Then he said oh, there will be an admin fee of R60 for the upgrade but nothing else. I agreed. No contract was signed, only permission to port my numbers to the new numbers. This month I received a bill from Neotel billing for both devices, plus a R65 ex VAT charge on each device plus an additional (double) service fee on both devices. I have logged a complaint at Neotel and no one has gotten back to me and I have emailed and contacted Hendri several times but he never answers my calls or emails. This is not fair and I will not be held liable for costs I didn't agree to. The billing must be corrected as I will not pay the invoice until it has been rectified. And I will not be held liable for interest on an 'outstanding amount' that shouldn't have been there to begin with. Is this how business is done by Neotel and MyNet, without any permission or signed contract for the client?? That is definitely not in line with current legislation!!</span></p>
