Sub-par experience

I've had 3 appointments so far to replace my prepaid meter. On day 1 they knew they could not fit it inside the wallbox, but yet they made two further appointments to only conclude they have to fit it outside. They also pitched on a Saturday without appointment and left a threatening letter saying my supply will be cut off if I don't cooperate within 14 days in my mailbox, NOT APPRECIATED! I'm not sure how this is the best company to be replacing meters in Cape Town.
