unfair customer service by Cell C

after having contract (data) for three years i then upgraded for the new 24 month contract, during that period i lost my WiFi router and i did a sim swap and put my sim card in my smart phone and ever since repeatedly i have to switch off/on my phone is i want to use my data which is an inconvenience. i went to my Mega-City branch for assistance without any luck, they escalated my problem to head office till today its been over 6 month now trying to solve a simple data connection problem.

i can savely say this is my last time using Cell C especially for data contract, from now i will stick to my trusted service provider

thanks
