ITC score not updated

Good day

Kindly assist, it has been 3 to 4 week that I have paid up my MTN account. However my status on my ITC score has not been updated . And each time I contact your company I am taken from pillar to post. This is bad business ethics and it is costing my business money. As I can't venture into other companies, this has affected my credit score as a result it has cost my business plans to fail or be delayed. I need this to be sorted in a matter of urgent . Ps: writing on behalf of a client
