some arbitrary monthly limit is placed on number of SMS we can send per month. This is done without any explanation and prior warning. Our customer care department is shut for nearly 2 days due to this. Despite contacting the support 4 times through different channels it hasn't been resolved. Ridiculous service and tech support. The people in the support call center seem to be be supportive and courteous, i think its just the engineering team thats absent and uninterested.
