SADV - ****************, NO FEEDBACK PROVIDED OR A SOLUTION- expected to pay for a service that I could not access due to it being their own error

I had signed up for Fibre at the beginning of March 2021. The line had been connected, however, the Service Provider whom were installing did not receive instruction to deliver a router as SADV had forgotten. Eventually on the 15th March 2021 after my numerous emails and follow ups, I received the router. On the 16th March 2021, after 1 active day of Fibre I was unable to use my Fibre. I called SADV numerous times and several consultants attempted to fix the issue at hand. There were many issues they had told me they had encountered; 1) a chord probably is not fitted into a port properly 2) I require a new router as my current router must be faulty 3) the line seems down and shows no connection. I called SADV numerous times and continued to email them as this effected my job as I rely on the internet. I had to purchase data to email SADV and sitting on the phone with them. Eventually on the 23rd March 2021 around 5/6pm I called and spoke with a gentleman- Moses. Moses was on the phone with me for almost 20 minutes. He then realised that my Username and Password needed to be changed, in a matter of seconds was my Fibre up and running. None of the other consultants had picked up on this issue and the error on SADV's part as there was no downtime nor was the cable nor router defective. Within this time and on that phone call and back dating to all the emails which I had sent SADV- I had disputed paying for 8 days of internet access that I wasn't able to use as a result of them not discovering the actual issue which was merely a Username and Password to be changed. I received an email that my account would be suspended on the 7th April if the account had not been paid. I had emailed SADV following up on this as I found it unfair to pay for a service I could not access and an error which was not my own. I had been emailing a lady in their accounts division Eileen Lekay and she advised that they offer "Best Effort Service" quite frankly the only effort being put in was one sided from myself. A service which I waited 8 days, for it to be rectified, I requested an updated statement and she proceeded to send me the initial statement. She advised me due to downtime that I could not be credited. However, this was not downtime it was an error due to ill-trained staff. I continued to request a statement and she then proceeded to ignore my emails as well as my phone calls. I called in around 3pm, 6th April 2021 and requested a manager to call me, I have not to-date received any calls/feedback or courtesy email that this is being rectified. I had sent an email this morning (7th April 2021) and had been ignored once again. I had called once again today and requested for an Ombusdman's number and to speak to a manager, I waited on the call for 40 minutes and no one answered. I then called back and spoke with a gentleman, Sayo who assisted with the Ombusdman's number, he advised me that they were in a meeting with the CFO discussing this and he advised that my Fibre had been suspended. I had no issue making payment but I had disputed the amount I would be owing over a month for the days the fibre was inaccessible. No employee of SADV has been in contact with me or advised me what is going on, I have had to sit on calls throughout these past two days running after a company, that quite frankly has been avoiding me and cannot provide me with an update. As a consumer I find it ridiculous, only when it has been time to pay SADV then have they contacted me but never addressed the issue at hand and that the onus falls on them. It is unacceptable to expect a payment for a service when you cannot provide one and an issue that was not because of a faulty line.
