Unbelievably bad service yet again!!!

Here we go again. Shocking service from Cell C, AGAIN! I don't know why I even bother phoning them as no-one is ever able to assist. I bought a new Experia XA1 on contract in November 2017, the last couple of days the battery life has changed from 24 hours to maximum 2 hours. Obviously there is something to be checked and fixed. However, to try and get assistance from Cell C is virtually impossible. I contacted Cell C at The Glen and was advised that the unit needs to be booked in for repairs ( no kidding!!!) but they cannot assist with a loan unit as all their loan units are in for repairs?????? I was advised to contact head office to assist. Upon doing so I was advised that head office does not cater for loan units and it has to be handed in at a branch, I was also informed that Cell C force the branches to keep loan units available. So the fun begins!!! I contact Cell C Southgate " sorry sir, we don't keep loan units"; Cell C The Glen "sorry sir, they are all in for repairs"; Cell C Eastgate "sorry sir, we have only 1 unit available but the screen is cracked". If some of the biggest shops are not able to assist, where would the client get assistance?????? So I contacted head office again, spoke to customer care again and was told that head office does in fact supply loan units????? ***!!!! Does anyone that work for Cell C head office actually know what the hell is going on there????? As usual, I have had to resort to media exposure to try and get some assistance from Cell C. I would not recommend this company to anyone that I come in contact with. Please refer to previous posts from me to understand the difficulty of dealing with this company.
