Non existent customer care

How can it be possible that there is no way to speak to an Mtn consultant? We have 3 contracts with Mtn, which 2 of is skye contracts, and after many calls to 135 and emails to *** , no one phones me back? We desperately need to change debit order details, rectify physical address and request to receive a monthly statement, and the customer service is just non existent? Our accounts is paid up to date every month yet we are not even able to speak to a consultant. If you don't come right on the Mtn app or with 135 options, there is no way to sort out my requests, the options is not on the app or on self service!! Don't even tell me to go to our local Mtn, firstly when i drive half n hour to our closest store, there is always system updates going on or our query can only be resolved over 135, nonsense. Yet when we took out the contracts they told us switch from our previous network (because of poor service) that Mtn can always help us. Well 3 contacts later and here I am on Hello Peter, hoping for anyone from Mtn to help me out. I am posting this on behalf of my father who is just as fed up as me trying to get hold of Mtn.
