Extremely bad service

So I signed up for WiFi with this company and I got one month free as a try out,the try out month was great didn’t experience any WiFi connection issues,the following month came I made a payment for the up coming month however just after I’ve made the payment all of a sudden the there’s interruptions on WiFi got in contact with with, I was told there’s 3ppp that needed to be added technician called and we did that over the phone but still the was no connect to the WiFi then I was informed that the matter has been escalated to an engineer and it will be fixed,I’m telling you I didn’t have WiFi from Thursday at 23:00 till this day and the worst part of it is that no one communicates I have to call and WhatsApp to find out what is the problem,they don’t have customer service skills,I called them this morning to find out if the engineer is getting something with fixing the problem or am I just waisting my time and money with this company
