Wow, worst service ever!!!

Contacted Discovery 2 months ago for a discrepancy on my tax return. the discrepancy was found, Discovery then did not want to change the tax certificate, rather refund me the money as a claim. This was in the beginning of March, now its close to the end of May. Numerous emails, phone calls to Discovery, not one answer, except "Morning sir

Nothing yet" over and over again. the last email I received was the end of April, 3 weeks ago, I have since emailed them 12 times, no responses. Tx Discovery, for nothing.
