No service, on hold for 6 hours.

Six hours on hold! My contract is due for upgrade or cancellation, and due to the Covid-19 pandemic and accompanying challenges I can not keep my contract. I was advised by multiple people that I can not cancel a contract in the store but I need to phone 135 on Monday 08/06/2020 as my contract ended on Sat 06/06/2020. I have been phoning since 09:12 and been on hold for a collective time of 6hours! With little to no help... Bianca from Menlyn Mall MTN tried to help me but she also has no authority to end a contract seeing as some brilliant person decided to create a department of retaining customers. and they can not answer a phone, but when you apply for a new contract, they can assist you within a few minutes, and cancellation takes days.
