Hypertension. Day and dilzem once a day?

I was on Dilzem CD 120 capsule twice a day for hypertension since 4 years. The reason for taking Dilzem is that due to a neuro medicine tryptomer which I took for headache my heart rate went up. Also at that time bp gone high. So cardiologist gave Dilzem CD 120 . Recently BP gone more high to 150/100 and sometimes diastolic pressure went till 110. So telma 20 was added. Then average bp became 130/90. Sometimes 120/86 . So cardiologist advised to stop one Dilzem and try. But again it became 140/100. So now should I go back to Dilzem 120 twice a day and telma 20 once a day? Or should I take telma 20 twice a day and Dilzem once a day? I got different suggestions from different doctors. Hoping to get suggestions.
