Worst service i have ever experienced

Every time I purchase electricity not using the registered account I have to beg them to switch on my electricity. They provided different bank accounts so that when we do a transaction from one bank to the same bank (fnb to fnb) the purchase is then allocated automatically but that is always not the case. I had to send them a WhatsApp which they take hours to respond and the y switched on after 2 hours, the next morning it was switched off again. I had to use my airtime again to call them to switch on my electricity which I had purchased the previous day from fnb to fnb but still it was not allocated. I always get ****ed with their service.
