HEROTEL - RECURRING SIGNAL DROP AND POOR TECHNICAL SUPPORT THAT DOES NOT RESOLVE THE PROBLEM

I AM A HEROTEL CLIENT AND LIVE IN OUDTSHOORN. I SELECTED "POOR' HERE BECAUSE OF THE INTERMITTENT SIGNAL WE HAVE HAD LATELY AND FOR THE LAST 2 MONTHS A TOTAL FRUSTRATION TO GET THE LANDLINE CALL CENTRE AND THE ONLINE (VIA WHATSAPP) TECHNICAL SERVICES TO ACTUALLY FIX! THE PROBLEM. PROBLEM: INTERMITTENT AND THEN NO SIGNAL DURING LATE AFTERNOONS AND PEAK TIMES IN THE EVENINGS UP TO 8.30PM FOR THE LAST 2.5 MONTHS. THE LANDLINE NUMBER IN GEORGE ANSWERED QUICKLY INITIALLY 2 MONTHS AGO WHEN I CALLED. THEY THEN RESET SETTINGS AND IT WORKED ETC...ONLY FOR THE PROBLEM TO PERSIST THE NEXT DAY. THEY THEN REFERRED ME TO THE ONLINE WHATSAPP SERVICE BECAUSE THEY SAID TECHNICIANS NEED TO DEAL WITH THE RECURRING PROBLEM WHEN IT OCCURS. ONE EVENING I WAITED FOR 1H30 MINUTES ON WHATSAPP WITH RESPONSE "ALL OUR TECNICHIANS ARE BUSY"...AND I GAVE UP!. A WEEK AND HALF AGO MY TENANT CONTACTED THE WHATSAPP HELPLINE WHEN THE SIGNAL DISAPPEARED...TECHNICIANS WORKED ON SETTINGS AND SAID THAT IT SHOULD "HOLD BETTER FOR LONGER NOW"....WHICH IT DID NOT! EVERY TIME WE CONTACT THEM THEY WORK ON RESETTING THINGS AND EVEN MENTIONING THAT THERE ARE MANY DEVICES CONNECTED TO THE MODEM WHICH WAS NOT THE CASE AT THE TIME. THIS MORNING SINCE 05H30 ...NO SIGNAL AGAIN! AND THEN IT CAME ON BY AROUND 08H00. I SPENT 1 HOUR ON WHATSAPP...."TECHNICIANS ARE BUSY"....AND NOW AGAIN FOR ANOTHER 15 MINUTES.."TECHNICIANS ARE BUSY". I CALLED THE LOCAL 044 LANDLINE NUMBER.. NO ANSWER FOR ABOUT 6 MINUTES... AND I HUNG UP. CAN SOMEONE PLEASE GET THEM TO FIX THE PROBLEM OR SEND OUT TECHNICIANS TO CHECK THE CABLES AND PHYSICAL CONNECTIONS!!!!!!!!???
