Do no trust MWeb!

On Thursday between 2am and 4am I lost internet on my fiber connection. Thursday morning at 9am I called MWeb to resolve the issue. I was unable to get any explanation as to why my internet was down, but was told it was a Vumatel issue. I spent from 10 am to 7pm on Thursday on the phone with various technicians, and not a single one was able to give me any information as to the failure of the internet. On Friday it was still not resolved- Mweb blamed Vumatel, and every call to Vumatel they would say its an Mweb issue. On Friday I spent from 7am until 6pm at home (missing my second full day of work) and had over 20 calls with Vumatel and Mweb and they still could not even tell me where the issue lay. On Saturday I called from 9am and was on the phone with various technicians until 7pm with still no resolution (around 12 calls)- no one even had a straight story as to what was happening. Mweb swore it was a Vumatel issue, and Vumatel swore that it was an ISP provider issue. After missing a full day of work on Thursday, another on Friday, (losing a vital contract because of my unavailability) and then a full day of calls on Saturday the issue was still not resolved. Not only that, but both companies are unable to even tell me what the issue is- I have been told at least 6 different stories (its my router [replaced that, same issue], its my modem [replaced that, issue continued], its my ISP [they set up a second account and that also didnt work], someone [they dont know who or how] changed my IP addresses, and many more) Monday came with the same results- another full day on the phone, expected to be at home waiting for a call that no one could even tell me when to expect. After no change the whole day I was told a technician would come and assist at 1pm. At 3:30pm there was still no technician (and I had missed another full day of work). They finally arrived (their manager had 'given them the wrong address') and spend an hour on site. They then left, promising I would get a follow-up call in the evening. This did not happen. It is now Tuesday and I still did not receive my call back. When I called in the morning to check why I was not called back on Monday I was basically told they dont know. Tuesday morning apparently Donovan the manager at Mweb was providing Vumatel with the info they needed (why this was not done on Thursday, Friday, Saturday, or Monday I have no idea) and would get back to me ASAP. This was at 11am. It is now 3:00, I have had no call back still, no internet for 6 days, and no one can even tell me why! Vumatel and MWeb have lost control or access to their network and this is a major security issue. I am very concerned, as I deal with confidential information for work, that MWeb and Vumatel is unable to control their own network. My trust in both companies has been destroyed, both by the failure of callbacks and the fact that I have spoken to over 10 people and no one has any control over their network. I would absolutely change my network provider, but as Vumatel has a monopoly in my area I cannot.
