poor customer service

Ive been renting a unit woth renprop since Jan 2016 and have been enjoying my stay,however about a month ago i was notified that some repairs needed to be done in the unit during weekends.on three occassions i made sure i stayed home but the contractors never showed up.This morning i woke up to an email from Ntombi Sibanda saying that repairs will only be done once i move out of the unit and that i would have to pay for those repaura or she would blacklist me.I dont know what kind of customer service this is because when i asked for proof that the contractors where indeed at my unit there wasnt any.i do not appreciate being threatened as i am a pying customer and have never given Renprop any problems.I asked why maintenance was not done befire i moved in,the answer i got was that there was someone sating in the unit,why on earth was i given a unit that still needed to be repaired,if tgey could not do the repairs while that person satyed in it,why are thy able to do tit while im staying in the unit.i am utterly disgusted by the level of unprofessionalism im receiving!
