Telkom BAD coverage

Telkom signal/coverage is down for hours on end - coverage seems to drop in the morning and then you have call the them and without fail they want to know what phone you have and then change settings, yet nothing has changed. When they eventually get the problem addressed it had nothing to do with your phone or settings - the service just all of a sudden works...... There is no recourse for Client to escalate the frustrations as Team Leaders do not have contact numbers nor do their management. So much for competitive costing when the service you rely on to work from home is always an issue and you wait days, if you are lucky to get it seen to.
