Avalon cemetery manager failed my family

About 2 weeks ago, I went looking for a grave of my late uncle at Doornkop cemetery. I found a tombstone of Moloi's on my uncle's grave, my surname is Zwane. I reported the matter to those at the cemetery, they gave me a number to call Shibari, I called, he said we should meet on Tuesday, (last week), I went there, he didn't come, I called him, his phone was off, I left my details and nothing happened. Today I went to see if he has done something, nothing at all. I called his supervisor Mam Thembi at Avalon cemetery, she said, she spoke to Shibari and he's coming, I waited for 1hr30 only when Shibari to say, he doesn't have a transport and he's not coming. When I called Mam Thembi, the office phone its not answered. I'm angry, they are black and they know how we black people feel about graves being disturbed. Moloi and Zwane, and people who suppose to fix things are ignorant and have lame excuse. They have failed my family, the Zwane. They need to fix this cause my ancestors can't have a Moloi tombstone.
