Afrihost OTP failure.

I changed my telephone number in November and asked Afrihost to update my profile. I jumped through all the hoops and they let me know it was done. Since that day I have not been able to get into my ClientZone as I do not get their OTPs necessary for logging in. I have logged numerous service requests and chatted to a number of staff and nothing. Nobody there has a clue how their system works. They have confirmed that my detail are correctly captured but cannot figure out where their system is sending my OTPs. I have asked to switch my OTPs to my email address but that is way outside of their training and understanding. Apparently my issue has been escalated to the developers but that they too are stumped by the seemingly complex nature of their own system. As with most businesses they too have let the skilled workers go after initial stability was reached. Pathetic really.
