Poor Customer Service or shall I say non existant

So I was advised via email to contact the Old Mutual contact center to get assistance with my app that tells me it has a different mobile number listed. I phoned 5 times and calls were disconnected and dropped. This chewed my airtime and still no closer to speaking to someone to get this issue resolved! Poor poor service from a company like this. Just get ignored and no call returned after they disconnected my call after sighing when I explained my query.
