Unable to contact MWEB good way to lock in customers

Its a pity there is no zero rating. We have been trying since October to get through to mweb. the only means of contacting them is via a phone call which we are failing at as the cellphone registered on the account was a company account which has been deleted as my husband was retrenched at Multichoice hence a one time pin cannot be received, the only way to get through to a human being is by entering this one time pin when the call is made. mweb has no email address or call me bak service or form online to log a query. we have countless issues where we have uncapped 100mbps line yet our wifi doesnt work. we were burgled and lines were tampered with and we cannot get through to them to send a technican. also we need to update the contact details on their system so that going forward the one time pin can be received to my husbands personal cell number but all this is impossible to do. MWEB seems to be a **** where they look in people to contracts then make it impossible to ever contact them again for servicing requests, now so dissatisfied we cannot even cancel as we cannot make contact. Surely service providers must have alternate means of contact. there are no mweb walk in stores. the one listed on google in centurion the phone number says does not exist
