Change of upgrade conditions on a whim!

I have been a client with Cell c since 2010. Never had any problems upgrading. I had a contract that was ending and I requested my one contract to be cancelled as it was ending. I had an accident with my phone on Saturday and I went to Cell C Clearwater on Sunday and was advised that I need to call the retentions department on Monday 30/08 to reverse the cancellation which i did. When I finally spoke to David at Cell C Clearwater he advised that he is waiting for approval fro my upgrade, Since when does that happen. I quote from Cell C upgrade conditions. There are several benefits to upgrading, including the fact that:

You receive a new phone of your choice from our wide range. You keep your cellphone number. There are no lengthy credit checks, especially if you stay on the same tariff plan.

Now please explain because I upgraded in April or june and there was no such thing. All of a sudden I am told because of the pandemic they need to do a credit check, I just copied and pasted that directly from the Cell C website. Now if this is not double standards then I dont know what it. I have four contracts with Cell C and all of them are up to date. I am so angry!!!!!!!!!! Cell C better get this fixed or I will report this to the ombudsman. What they state on their website is what needs to filter through to all departments.
