Bad service and communication

It’s my 4th month of me asking VEGA to update my account statement so that I can get my certificate. I’ve been making them monthly payments and sending POPs immediately after, however they’ve failed to reflect some payments on my statement. I’ve been asking them to rectify this for months, and resent POPs, sent multiple emails to no response. Their service is absolutely ********** I must say, the entire process of trying to communicate with them is painful.
