Online Store is an absolute disgrace!

I app**** for a contract online. Got met with an approval with conditions which is understood since I just came out of debt review. I tried contacting the online department to find out which phones I qualify for. Upon calling, I am met with "We've picked up an unusually high volume of calls from your phone to our call center and have blocked your number". It is me phoning and every time I phone I pass the security checks. Why is my number being blocked? You guys keep telling me to speak to Tobi on whatsapp but all that thing does is try tell me my airtime balance. This service is absolutely pathetic and I am truly considering porting out.
