Cell C contact data

On the 3/06/2019 I was called by one of consultant (Clive) from Cell C, he called to upgrade my contact data to R89. After the upgrade then I realized he added data of 90 mb, 90sms & 90 free minutes.I had 1.7GB remaining and 14.50 airtime left before upgrade.All of a sudden they were all wiped off. I tried to call back on the same number he used to call me 084135 but kept on getting cut offs when they tried to be transferred to him , I called again spoke to Andrew but could not get Clive back as the call kept on disconnecting, Tuesday he called and told me he was aware my Data that was hanging on the system then adviced me to switch off my phone and everything will be sorted afterwards, but nothing updated into my account. He called for something like 3 times asking me to repeat the same exercises but with no results. Wed nothing & I called again with no luck of getting any assistance from them, I even lost count on number of times I had to call back. Friday I called again and this time I was very angry because my phone data stopped working completely after I had to buy airtime of R15 and data of R29 , but data still disconnected. I called Cell C explained to them I unable to use my data bundles as there was no connection of watsup data that I activated with R20 but nothing could work on my phone , my phone was disconnected for the whole entire day I could not connect with anyone. I spoke to Andrew again explaining the same stories. He then transferred to a technician by the name of Thabisa who showed no interest to assist me, she told me it’s my phone settings. I feel if I was never called for upgrade I wouldn’t had went all through this drama, but because of incompetency of staff from Cell C had to me inconvenienced the entire week without using my phone in peace like before. I want all this sorted out by Cell C without me having to call again and send from pillar to post. I want all my money that I had to spend paid back and all my remaining data and airtime loaded back into my account. Last but not list my phone connected back because even now as I’m typing can’t use my phone. What a bad experience I had with Cell C and it’s not the first time.
