Awful Customer Service

Over 2 months ago, I was offered a new Clicks card from a clicks store as mine was old. Really great service so I agreed, the manager of the store then told me not to worry my new card would be linked to my old card so I would still get all my rewards. <br> <br> Since then, firstly my new card wasn't activated for almost 2 weeks, once activated after numerous calls to the call center, it still didn't reflect my points. I call in, they give me my old card number and redeem my R90+ cash backs from my old card and told me it would be linked after their month end. Since then I have received more cash backs on my old card. But the account has still not been linked <br> <br> I have called Clicks 7 times, emailed numerously each time I get told it will be done. Yet to date 2.5months later nothing has been done. Only feedback I received was them telling me that IT was busy with the issue three weeks ago when I called?
