Mtn bad service

Struggle with mtn. Local shops can quickly upgrade but when contract comes to an end, local shops cannot assist and ,135 ,must be called.

They answer and give ref nr ***. Then have to hold and listen to music for retention dept.

After 3 hours still no person talking or answering so that we can say that by 23 April mtn must know that we do not plan to continue with the phone or contract as it is coming to an end.

The phone was used by grandchild but she now has her own contract and we do not want to continue with this phone anymore.

Not happy.

Contract phone is ***.

Very bad service.
