Call Centre Poor service assistance

From approximately the 20th of November I have been struggling with your network signal, in the bigining it was jumping from full signal to one bar the entire time. Then since Sunday 28th no internet signal whatsoever. After numerous attempts I mange to eventually get hold of one of your agents at the call Centre. The lady whom assist was very friendly and helpful, after conducting some testing I was told that the problem seems to be with my rain sim card not connecting. I was informed that a person from support will contact me to assist. I have send numerous tickets for assistance in this regards but Up to date one has contacted me. I have secure a new rain sim from one of your retail partners, and need to activate this on the existing account, but can not manage to activate this online. Also to date not been able to get hold of your call Centre since Monday call different times during day and after hours but always the same calls get dropped constantly. Either the problem with your system or your call center agents. Also email adres as per rain website bounce back stating addres not found. I don't know why rain make it this difficult to sim swap and re connect to your services. And not been able to reach your call Centre is a definite no no. Why do you have a call center if they do not add value to your business or assist and serve your valued clients as a call center is supposed to do. I think rain your call center is a detriment to your business please urgent attention needed in this regard. I have been a loyal customer of rain for the better part of 2 years and never any complaint on the contrary I have referred many friends family and colleagues to you. And would like to continue this business relationship. So please get someone to phone me as a matter of urgency to sort this problem to register my newly acquired rain sim and get me reconnected to the network. Looking forward to your prompt response Kind regards S. Nicolay
