Worst customer service I have received in a long time

Been a customer of wirulink for a few years and always a very happy one. Until around a month ago when things went south. Internet and landlines stopped working and they took four days to come and try sort it out. First I was told they have no support on weekends (we are a hotel and busiest on weekends) and then someone admitted that the support crew suppose to work on weekends decided not to do as there was a dispute. I got angry and spoke to every person on the support department probably more than a 100 times in the following week and they sent around 3 technical teams but they were all clueless and couldn’t solve the problem. After shouting st them st the phone I managed to get through to a manager, Shannon, who made promises to solve the problem ASAP but after another three teams sent here in different days the problem persisted. Eventually a tech guy called Nelson came and managed to temporarily solve the problem. Tried to get hold of the managed several times to arrange a credit for the over Two weeks I had no internet for but to no avail. I asked several times for a manager to call me and I only managed to speak to one once and every other attempt to do so has resulted in no one bothering to call me. I am a business owner and when a customer is upset I pick up the phone inmediately and I face the problem head on but in this company no one takes responsibility and does exactly that. Quite disappointing as I have supported them for years. I see they have grown very fast but their technical department hasn’t in the same measure and they are few and extremely unprepared and not qualified to help the customer. I am not the kind to go to social media and complain but I feel they need a wake up call otherwise tha business is going under. I have contacted some of my neighbors and they are experiencing similar issues
