Struggling for more than 2 weeks

We have had intermittent connection problems since January this year. The problem is that my connection is on and off day and night. (We've been on telkom mobiel for 4 years in the same location and haven't had this problem before)<br> I called Telkom and logged a fault on the 1st of Feb (***). I held on for more than 15 minutes.<br> On the 3rd they called, but I missed the call since I was working. They sent me an SMS to say I must call the call centre again.<br> I phoned again on the 3rd of Feb (call lasting 14 min 20sec) and logged a fault.<br> On the 4th of Feb they called me and said a technician will contact me.<br> No technician called.<br> On the 10th of Feb I called again (call lasting 15min 34sec).<br> Up until today I haven't heard anything and I still have the same problem.<br> Please help me sort it out.
