Technical service at Mweb

I am extremely frustrated as I have no internet and no response occurs when sending emails to the technical center. I have a pay as you go contract and cannot wait on the phone to be helped as all my airtime will be used. I have been number 32 and upwards in the queue waiting to be helped on the phone Due to electrical cuts the Mweb device needs to be synchronized again with the Vumatel router. An impossible task as no none responds to emails.
