Hi - Attitude

Hello, After a frequent calls to rental agency one final day they responded on my request to check electrical stove issue and drainage block at tub & wash basin in my home. They register the maintenance complaint and sent a person after 2 weeks(I did remainded to send person to inspect the issue). Person came and inspected and said stove is fine and need to apply fluid to clear drianage block in tub & wash basin. I asked them did i need to pay/charges for the service&material, they said no need to pay anything from my side(as tenant) its all cover in the maintenace. I said OK to fix the issue. Issue got fixed and later 1 month i got SMS, saying that i need to pay R725 for the service. I got shocked, i do not have any information, either invoice or statement on this from rental agency. I contacted the rental agency, i got regular(as usual) answer that contact person is busy. I requested the customer care person to responde to my email. contact person sent response to my email like \ Should you wish to dispute this matter further
