Unacceptable services

Apologies for this lengthy complaint but it is necessary for a detailed explanation for prospective clients: I have been with Vox for uncapped wifi for a few years. I then purchased an UPS device so that I have uninterrupted wifi during loadshedding but was never pleased with their accounts department. Last month I tried to change my banking details for debit order deductions but it took forever to get a response. I had a problem with an unauthorized debit order and removed my funds to my credit account. I then made direct payments (Vox included) to my other two accounts BEFORE the debit orders were due. I informed them in an email that the debit orders WILL BE UNPAID because of a problem at my bank and sent the proof of payment (eft). They still charged me a fee for the unpaid debit order. I accepted it. Then, on 8 April this year, I purchased a software program because I can pay a monthly amount rather than one payment - I am a pensioner and it would be easier. I struggled to download it because I did not have sufficient disc space. I called Vox to cancel the purchase. When I said to him that I will have to purchase a new laptop to install it, he should have told me that my new laptop would come with the software installed. He did not, instead he encouraged me to keep it for the new laptop. That was a day or two after I purchased it. Now, I get an invoice for almost R600 cancelation fee because I canceled the contract within the contract period. I tried to explain to them that I did not use the software because I could not download it but NO they will not budge. Please be careful with Vox when you purchase any of their software programs. Make sure that you are able to download it before accepting it. The full annual price is about R800 and they charge me R600 for three weeks!! A complete ripoff! I think they should consider my history with them (how long I have been a client) as well as the fact that I never skipped a payment (other than the unpaid d/o explained above and that I am a pensioner. I'm so terribly disappointed in Vox
