Disgruntled customer

I am extremely disgusted in their services, I would normally buy a voucher through their portal and it would be a Mitchell's Fibre one, however when I bought a voucher last night, VUMA was the only one available, the voucher went through but all my login details got changed by mweb and the wifi is running but I am unable to connect, I've been waiting over an hour already for a tech support to answer the phone but to no avail. I paid R399 for not internet connection.
