More than 2 years and this is the type of service i get

This is a horrible company and i am fed up already - i changed my bank account details and informed the new bank to put it on on their side ,however the person failed to do so, and my device was switched off as well as my sim ,I notified them that this is my new bank details and they can deduct, which nicole did. The debit order went off and my sim was not active nor my handset. i reset my handset and they put a block on it which disable me from entering the google sign in details. eventually after 3 days after the DO went off my sim worked . I have sent them many emails - Now they said because i reset my device they need to come and collect it and I need to pay R150 on collection and R150 on drop off. i notified shamiema that i do not have money at all she made arrangement with her manager to have it debited from my bank account on the 25th(this was said on the 9th November) i notified her that i will get back to her- the next day i sent a email to *** notifying her that she can do that arrangement(10 November) i received no feedback i sent another on the 11th nov ,no feedback, and i sent yet another FUP email using the same email threa d,no response today was the last and i started swearing in my emails by this time . i called in a lady answer and when i got upset she dropped the call in my face, i called in again spoke to yandiswa, very nice lady ,she was advised by shamiema that they apparently never received confirmation from me to confirm they can do the transaction!! Like no one reads the contactus emails but they were quick to tell me about the money that did not go through !!! serious i am not impressed. For the last 2 years i had no issues and now with the upgrade im getting terrible service. please resolve this and have my handset collected today!!!!! and dont let me only receive it back after the DO went off month end Thank you
