Indifferent & *********** servicing and repair of DQ (***) tracking device

Shocking! After experiencing repeated battery failure I asked for an assessment of my tracker as these units' batteries have been known to drain car batteries (attested to by both of my parents!). About mid-October I scheduled an appointment. The earliest was a week later (in the interim, I had to push-start my vehicle). Accepting the delay, I was then advised that the unit hadn't been replaced or upgraded since 2012, when it was first installed. Fine, I thought, these things happen and I accepted the day it took to replace the unit. Then I was asked to wait another day as the installing agent (Desmond) needed to upgrade software or such as he didn't have same available to him. Fine, I accepted this too. When done, I was asked to go for a "long drive" (piece of string) in order to recharge the car battery fully. When repeated trips failed to recharge the battery enough for me to avoid push-starting, I called for assistance and to see if Discovery would cover the cost of a replacement battery. By this time, another week of push-starting had been endured (luckily I'm healthy and fit enough to manage and have a sloping drive-way where I live and work). I waited a few days, push-starting my car or leaving it running where I could, expecting to hear a simple 'yay' or 'nay' from Discovery re replacing my battery. I called Discovery TWICE more over the course of a few days and still wasn't able to contact anyone who could help me or advise me what their (Discovery's) response was. I noted a missed call or two, over the course of a few weeks, which calls I'd missed as I was unavailable...notably, these calls where only made late in the day at around 4pm. I've now been push-starting my car for a month, while Discovery has ***********ly handled a very simple operation. The onus is on the company to maintain the tracker system and I feel that I should not be accountable for their ineptitude. I'm still waiting on hearing from a bright spark who's able to feign concern for my predicament and assume enough of a competent front to explain why I should have just replaced my battery independently! I spend my money on insurance against eventualities...the only threat to my vehicle's condition is YOU, DQ-***!
