Telkom's disgusting service and disrespect to the customers

the most disgusting service ever received, on the 17/09/2018 I bought an eezyvoucher to recharge like I always do. I tried to recharge and I get an error message saying that I have been blacklisted from recharging and should try the next day. so I call the call center and the agent I speak to says she cant help me because their systems are down but she also says I should try again after an hour. so later after 2 hours I try again and I get the same message. I left it overnight and this morning the 18th/09 I tried again and it tells me the same message . so I call again, the first agent confirms that the blacklist is cleared, then I try recharge again and I get the same blacklisting message. I then call for the third time and the agent puts me on hold to unblacklist my phone then I wait, she comes back and also confirms that she's removed the blacklist. she confirms that there was a blacklist but she undid it. I ask what caused it she tells me that I must have tried recharging more than 4 times, I tell her that I only attempted to recharge once and I got this message. so she insists that its fixed now, I can put the phone down and try. I did put the phone down and I tried again and guess what I got the same blacklist error message. so all these agents are lying to me not to mention inconveniencing me as I bought data because I need to use my phone. not so long ago I complained about the network coverage since I am permanently roaming on MTN and cant use any of the extras they give us for purchasing their product. I spoke to a manager and he rudely asked me if I knew how much it cost to built a base station. by the way I live roodepoort by westgate mall and not in the rural areas. everywhere there is no network coverage even in Soweto. I am permanently roaming with MTN. they have systems that are not working and *********** staff who dismally fail to address their clients , they are rude and they just blatantly lie just to get you off the phone. extremely disappointed and disgusted at Telkom
