No Fiber after line speed upgrade

Hi

I recently upgraded my line speed and I have had no finer since. Afrihost said all is ok on their side but I am still not getting a default gateway when I connect directly to the Ont from my pc. Has lease if someone could assist me from frogfoot as it’s been almost 24hrs now. We loaded a fault with frogfoot earlier in the day “ Here is your reference number: FRG831807-RCB-B1” the I got a sms saying “ Good Afternoon Nathan Frogfoot reports the reprovision was a success Kindly test on your side. Kind Regards” but will I have no Fiber. All my Ont lights are green. We then loaded another fault last night “ Afrihost has logged a fault ticket with Frogfoot "FRG831807-RCB-B1 line goes down after each upgrade" Ref:GSM-***6. We apologize for the inconvenience.”

Please help me out

Thanks

Nathan
