I sent them an email on the 8th of April 2021 an application for dispute resolution form. I received a non reply mail from them and they told me that someone will contact me within 10 days. I tried to phone but they couldn't assist. I mailed them about 5 times and phoned them about 10 times and nobody could assist me. It looks like their staff is ***********. I need their help urgently and would like someone could help me to resolve my problem. I'm from gauteng my email address is *** and my phone number is ***
