Telkom LTE home and mobile

We have been using Telkom LTE for our home internet for quite a few years. We get very good speeds and few connection problems. Now with the high load shedding stages I have been looking into getting a UPS so I can still work when the power is down. But it does seem as if the Telkom signal itself is very low after about 2 hours of load shedding, so was thinking of changing to fibre. But the many negative reviews of the service providers has frightened me off fibre! I have not tried to phone Telkom for any queries, but go into the nearest Telkom store (at Blue Route Mall) where the staff are friendly, helpful and knowledgeable. We also use Telkom for my husband's mobile voice and data and we're very happy with that. There have been occasional outages, but actually can't remember when that last happened.
