Terrible Service!!!!

I have joined Mweb since June 2018 and every month I have to call in to find out if they have received the proof of payment for the monthly fee. I have explained every time I called that I use the Capitec App and it does not give me the option to insert a ref number. I spoke to a second in charge(2IC) in June 2019 and he gave me a step by step instruction on where to insert the ref number using the App but it still did not work. I emailed him the proof of payment on the 03/07/2019 and up until today I have still not received any feedback. I had to call in again today and they said I should email my proof of payment to *** (which I have been doing every month since June 2018) and it will get allocated from there. It is almost 2 weeks since I emailed it to that email address but it was still not allocated, the agent advised me that the turn around time is 24 - 48 working hours. I find this really hard to believe and not acceptable. I want a manager to contact me as I refuse to keep calling every month!!!!!! The agent also advised that there is nothing else that can be done. This must be the worst service provided and I will share this on every social media.
