HC failed to update my number

I have been trying to update my number but the support team has been ignoring me.

So I want to buy from HC, emailed them to ask for cell number update they asked that I send certified which I did. I sent it in august but never got a response. Called them and spoke to 2 agents and was told there was an issue with my account someone will call me back to explain but no one called. All I need is just a cell number update so I can access my account. What could be difficult there.

I commented of their Facebook profile on my frustration and Tebatso responded via inbox asking me questions leading to my frustration. After I explained everything she tells me I don’t qualify for credit because my account was settled through legal. That is a 2018 account she is referring to which is ok but why did she assume I want to buy on credit? I did not confirm how I will make payment all I said was that I want to buy hence I need to access my profile. She then closed our conversation without even check how I was planning to pay for the items I need to buy. Nor even explain that accounts similar to mine can never be allowed to buy from them again. I have received a horrible support from this team it is disheartening how they treated as a customer.
